NPC Mannequins in Survival

This release supports Paper running Minecraft Java 1.21.9 and 1.21.10. It may work on future Minecraft versions, but it has not been tested.

• Spawned mannequins now mirror the player's rotation
• By default mannequins will be looking at the player and straight ahead
• Crouching when spawning a mannequin via a soul will cause the mannequin to copy the pitch of the player's head
