Updating Pack to function with all versions of Minecraft between 1.21.5-26.1.2.

Discontinuing official support for versions before 1.21.5. Mods have existed to allow this to happen in some capacity but development for those versions of Minecraft (when juggling using the mods and also the core shaders that allow for the emissive item effect to occur) has been more than I want to take on at this time.

Updating to 1.21.11 along with a bugfix with Sweeping Edge's closed book model that was causing the entire pack to not work. Also added a placeholder for Lunge's books so that they would render properly. Unique models and textures for Lunge will be added at a later date

Now with support for older versions of Minecraft, using Pommel!

Pommel currently supports MC versions 1.20.1, 1.21 and 1.21.1

1.21.6 removed the need for models to have a rotation step of 22.5, with that change we have made the feather falling wing animation smoother :)

Fixed a bug with core shaders that was causing this pack to fail upon loading
