Immutable Components

[williambl]

wip...

• methods on ImmutableComponentKey to get data / modify data without directly using the ImmutableComponentWrapper
• support for attaching to things other than entities (lol)
• support for registering custom ImmutableComponentHookTypes?
• much cleaner code (it's written to work rn, not to be readable lol)
  • on that note, comments / javadoc... things which im not sure how im gonna fix them:
• support for registering listeners from client side
• NAMES !!
  • immutablecomponent is STUPID
    • datacomponent would be perfect but its ALREADY TAKEN by mojang
  • ~~uhhh idk what to call these callback things like on tick, and you can tell because they're called like 3 different things in code~~ called them hooks
• hooks are associated to a pair of (component ID, owner class) but this isn't uniquely identifiable of a component implementation (b/c of entity predicated factories and stuff)
