The right/left ears, and four legs of a panda cannot be independently retextured

The right and left ears, and all four legs of a panda cannot be independently retextured from one another, resulting in them always looking the same. This is limiting to a player's creativity and ability to modify the entity's texture.

Steps to Reproduce:

1. Download and apply the provided resource pack:
   

1. Spawn a goat

Observed Behavior:

The panda's two ears and all four legs will look entirely red, despite the player seemingly only modifying one of each in the UV map.

Expected Result:

Only one of the panda's ears and legs would be altered, since that is what the player intended to change. The current behavior is unexpected and not resource pack friendly.
