Register turtle upgrade models separately

ITurtleUpgrade.getModel has always been rather error-prone to use, due
to its client-only nature. As ModelResourceLocation is now client-only
again in Forge 1.19.1, no seems a good time to fix this.

The getter for models is now a separate interface inside a new
dan200.computercraft.api.client package. These are registered
per-TurtleUpgradeSerialiser (as those should correspond to class
anyway). It's a little ugly, and we may rename the XxxSerialiser classes
to something more general in a future update.

I'm not wild about the interface here either - happy to change it in
future versions too.

   * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

Also clean up the generic arguments to IUpgradeBase/UpgradeSerialiser a
little bit. It's not great (wish Java had HKTs), but it's better.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, caste, color, religion, or sexual
+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall
+  community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of
+  any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address,
+  without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+"conduct AT squiddev DOT cc". All complaints will be reviewed and investigated
+promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.
+

+# Setting up GPS
+The @{gps} API allows computers and turtles to find their current position using wireless modems.
+
+In order to use GPS, you'll need to set up multiple *GPS hosts*. These are computers running the special `gps host`
+program, which tell other computers the host's position. Several hosts running together are known as a *GPS
+constellation*.
+
+In order to give the best results, a GPS constellation needs at least four computers. More than four GPS hosts per
+constellation is redundant, but it does not cause problems.
+
+## Building a GPS constellation
+![An example GPS constellation.](/images/gps-constellation-example.png){.big-image}
+
+We are going to build our GPS constellation as shown in the image above. You will need 4 computers and either 4 wireless
+modems or 4 ender modems. Try not to mix ender and wireless modems together as you might get some odd behavior when your
+requesting computers are out of range.
+
+:::tip Ender modems vs wireless modems
+Ender modems have a very large range, which makes them very useful for setting up GPS hosts. If you do this then you
+will likely only need one GPS constellation for the whole dimension (such as the Overworld or Nether).
+
+If you do use wireless modems then you may find that you need multiple GPS constellations to cover your needs.
+
+A computer needs a wireless or ender modem and to be in range of a GPS constellation that is in the same dimension as it
+to use the GPS API. The reason for this is that ComputerCraft mimics real-life GPS by making use of the distance
+parameter of @{modem_message|modem messages} and some maths.
+:::
+
+Locate where you want to place your GPS constellation. You will need an area at least 6 blocks high, 6 blocks wide, and
+6 blocks deep (6x6x6). If you are using wireless modems then you may want to build your constellation as high as you can
+because high altitude boosts modem message range and thus the radius that your constellation covers.
+
+The GPS constellation will only work when it is in a loaded chunk. If you want your constellation to always be
+accessible, you may want to permanently load the chunk using a vanilla or modded chunk loader. Make sure that your 6x6x6
+area fits in a single chunk to reduce the number of chunks that need to be kept loaded.
+
+Let's get started building the constellation! Place your first computer in one of the corners of your 6x6x6. Remember
+which computer this is as other computers need to be placed relative to it. Place the second computer 4 blocks above the
+first. Go back to your first computer and place your third computer 5 blocks in front of your first computer, leaving 4
+blocks of air between them. Finally for the fourth computer, go back to your first computer and place it 5 blocks right
+of your first computer, leaving 4 blocks of air between them.
+
+With all four computers placed within the 6x6x6, place one modem on top of each computer. You should have 4 modems and 4
+computers all within your 6x6x6 where each modem is attached to a computer and each computer has a modem.
+
+Currently your GPS constellation will not work, that's because each host is not aware that it's a GPS host. We will fix
+this in the next section.
+
+## Configuring the constellation
+Now that the structure of your constellation is built, we need to configure each host in it.
+
+Go back to the first computer that you placed and create a startup file, by running `edit startup`.
+
+Type the following code into the file:
+```lua
+shell.run("gps", "host", x, y, z)
+```
+
+Escape from the computer GUI and then press <kbd>F3</kbd> to open Minecraft's debug screen and then look at the computer
+(without opening the GUI). On the right of the screen about halfway down you should see an entry labeled `Targeted
+Block`, the numbers correspond to the position of the block that you are looking at. Replace `x` with the first number,
+`y` with the second number, and `z` with the third number.
+
+For example, if I had a computer at x = 59, y = 5, z = -150, then my <kbd>F3</kbd> debug screen entry would be `Target
+Block: 59, 5, -150` and I would change my startup file to this `shell.run("gps", "host", 59, 5, -150)`.
+
+To hide Minecraft's debug screen, press <kbd>F3</kbd> again.
+
+Create similar startup files for the other computers in your constellation, making sure to input the each computer's own
+coordinates.
+
+:::caution Modem messages come from the computer's position, not the modem's
+Wireless modems transmit from the block that they are attached to *not* the block space that they occupy, the
+coordinates that you input into your GPS host should be the position of the computer and not the position of the modem.
+:::
+
+Congratulations, your constellation is now fully set up! You can test it by placing another computer close by, placing a
+wireless modem on it, and running the `gps locate` program (or calling the @{gps.locate} function).
+
+:::info Why use Minecraft's coordinates?
+CC doesn't care if you use Minecraft's coordinate system, so long as all of the GPS hosts with overlapping ranges use
+the same reference point (requesting computers will get confused if hosts have different reference points). However,
+using MC's coordinate system does provide a nice standard to adopt server-wide. It also is consistent with how command
+computers get their location, they use MC's command system to get their block which returns that in MC's coordinate
+system.
