Added support for the new CustomModelDataComponent

[BlitzOffline]

Adds a new per item option model_data_component. It makes use of the new CustomModelDataComponent API introduced by Spigot in 1.21.4 as a response to the custom model data changes made by Mojang.

Example of usage:

items:
  test:
    material: dirt
    slot: 0
    model_data_component:
      strings: ["string1", "string2"]
      floats: [1, 2, 3]
      flags: ["true", "false", "true"]
      colors: ["255, 255, 255", "0, 0, 0"]

It will work with the has item requirement. Since it is now a component, it will be an unstrict check. If all the specified values exist in the checked item, it will be considered valid even if it contains more elements than the ones specified.

Closes #165

Tested by:

• zenkokasai in discord
  • Tested the floats option with placeholders.

Note: The old model_data option will continue to work.
