Optimized pack icon, minimized json for modrinth releases

Make some items look nicer in shelves

Refactor the entire pack, drop any model recreations and instead always call the block model when possible, cut most dependency trees, remove every block model overwrite

Adjusted everything to look in good in every possible scenario(inventory, dropped, third person, item frame etc.) including unique interactions when equipped in the head slot

Version compatibility now from on 1.20 onwards
