Fabric lol

- Add support for Fabric. This is mostly pretty simple, though does
   require a lot more mixins than Forge.

   Half this diff is due to data generators: we run them separately as
   some aspects (recipes mostly) are different between the loaders.

 - Add integration with Iris (same as our Oculus support) and REI
   (mostly the same as our JEI support).

 - Generic peripherals only support inventories (or rather
   InventoryStorage) right now. Supporting more of the Fabric storage
   API is going to be tricky due to the slotted nature of the API: maybe
   something to revisit after Transfer API V3 (V4?, I've lost track).

Note, this does /not/ mean I will be publishing a Fabric version of
CC:T. My plan is to rebase CC:R on top of this, hopefully simplifying
the maintenance work on their end and making the two mods a little more
consistent.
