Guard Villagers (Fabric) Fork

Initial version of the unofficial fork of GuardVillagers. Supports Minecraft version 1.21.4 (bumped from 1.21).

Additional changes include:

• Crossbow guards no longer overshoot their targets
• Bow guards AI fixed (guards can use regular bows again)
• Melee guard pathing behavior updated to prevent "moonwalking" and not attacking

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.
