Variants-CIT

• Added the custom_name CIT module
• Fixed the parameters block being mandatory on modules with only optional parameters.
• Fixed items with no variant using the fallback model instead of the vanilla one.

⚠️ This release contains breaking changes. ⚠️

• Overhauled the mod to serve as a multi-purpose CIT library. Renammed mod to "Variants-CIT".
• Removed the embedded resource pack. See the main page for a list of compatible packs.
• CIT logic is now modular, and can be extended by other mods.
• Added CIT modules for the Axolotl Bucket, Goat Horn, Music Discs, Potions, and items with custom_data.
• CIT modules must now be enabled and configured by resource packs, which require additional files.

• Added the ability for resource packs to define CITs based on enchantment levels.
  (However the embedded pack does not use this feature.)

• Fixed an incompatibility with ModernFix, that could prevent enchantments with no CIT from using the vanilla texture.

• Initial Release
