This adds SPDX license headers to all source code files, following the
REUSE[1] specification. This does not include any asset files (such as
generated JSON files, or textures). While REUSE does support doing so
with ".license" files, for now we define these licences using the
.reuse/dep5 file.

Peripherals can now have multiple types:
- A single primary type. This is the same as the current idea of a
type - some identifier which (mostly) uniquely identifies this kind
of peripheral. For instance, "speaker" or "minecraft:chest".
- 0 or more "additional" types. These are more like traits, and
describe what other behaviour the peripheral has - is it an
inventory? Does it supply additional peripherals (like a wired
modem)?.
This is mostly intended for the generic peripheral system, but it might
prove useful elsewhere too - we'll have to see!
- peripheral.getType (and modem.getTypeRemote) now returns 1 or more
values, rather than exactly one.
- Add a new peripheral.hasType (and modem.hasTypeRemote) function which
determines if a peripheral has the given type (primary or
additional).
- Change peripheral.find and all internal peripheral methods to use
peripheral.hasType instead.
- Update the peripherals program to show all types
This effectively allows you to do things like
`peripheral.find("inventory")` to find all inventories.
This also rewrites the introduction to the peripheral API, hopefully
making it a little more useful.
