Updated with a bunch of new 1.21.2 features.
Changed all textures and related models to use the item_model component. This allows for far better compatibility with other datapack's content as you don't have to worry about overlapping base items.
Added relevant repair materials for every item
Implemented the Equippable component for all boots, and added textures for each of them on the worn armor model.
Updated to 1.21.2 and 1.21.3 Updated all recipes into the new format. Fixed all the issues with the new attribute format. Added repairable materials to all items.
Did not add textures to the worn armor model, but am looking to do that. Wanted to get a functional version of all my packs out first.
