Switch to Brachyura

[DragonEggBedrockBreaking]

• I had to manually get the permissions API due to maven being crong
• I had to split up fapi modules due to brachyura not being able to handle pom files
• I tested that it worked in an IDE, that it builds, and that the game launches in a dev env - no other testing done since idfk how this mod works or wtf it does...
