Elytra Trims

Added

• Runtime trim generation

This is an experimental feature. Please report any issues with it on the GitHub page!
Like, really. I don't know how it will behave in many possible combinations of other mods and datapacks

Explanation:

This feature listens for every registered armor trim and attempts to register it again, but for elytra's path. As the result, you don't need to specify armor_trims.json atlas source.

A specialised resourcepack is still needed to provide textures for trim patterns, but it works well for datapacks or mods adding new materials.
