Better Animations

Part 3 to the code rework, should provide a significant performance improvement

Part 2 to the code rework

Codebase update

The falling/burning animation no longer plays when blocking with a shield, meant to reduce jankiness during pvp.

Now requires emf v2.1.0 atleast.

Updated and tested on 1.21.1
Further refinements to legs while floating in water

Fixed some issues from the previous update breaking some older animations while swimming and gliding with elytra

Added leg movements to the 'in water' animation

Added a paddling animation while not swimming but when the player is submerged in water.

Part 2 to a flying update:
Fixed some critical bugs with head movement when flying and legs, made leg animations more subtle.
