Architectury Update

- Cache fractions from -1024 to 1023
- Add BiomeModifications for platform-agnostic biome additions
- Add FluidStackHooksForge to convert architectury FluidStacks to forge FluidStacks
- Migrate to Forge Loom & Update Architect Plugin
- Mark several methods in Mod as NotNull
- Add Env as a replacement for EnvType

 ### What is Architectury
 Architectury is an api to abstract calls to fabric api and forge api as both loader has different implementations of what can be perceived as the same thing.
 
-Architectury updates regularly, with new hooks and features. Currently contains over **60** events hooks, networking abstraction, loader calls abstraction, game registry abstraction and an easy to use @ExpectPlatform annotation.
