Guard Villagers (Fabric) Fork

Fixes some armor rendering that didn't match the original version of this repo from mrsterner for 1.21.4.

Updates to shoulder pads:

• no longer show through chest armor
• slightly rotated downward to match original version

Updates to quiver:

• updated quivers to match the slight offset on the back as found in the original version
• no longer intrudes into the head.
• now sit off of chest armor slightly more to prevent armor rendering into the quiver.
• size was slightly reduced.
• only renders if not holding a bow or a crossbow

Known Issues:

• Bow guards that have an active target have a tendency to take paths that incur fall damage when no other path is available.
• Melee guards with shields can get stuck in a permanent blocking-only loop when 1v1 against a ranged mob.
