Enhanced Keybinds v1.2.0 for 1.21.4

More Binds and other things! - 1.2.0 (Skipped 1.1.0 here on GitHub 🤔 )

• Added keybinds from the Skin Customization menu!
• Added configuration to include individual skin layer binds (disabled by default)
• Moved ClothConfigScreen to new "screen" directory
• Fixes a weird mixin bug that randomly crashes the game (thanks Trinity and Pug for testing!)
• Includes Cloth Config! Cloth is embedded and is not required as a separate dependency!

I am aware of a pretty annoying bug, where modifier keys cannot be bound by themselves and I plan on fixing this with the next release. I might need to totally rewrite the multikey system again :/
