Fix Sheep Girl for Anime mob girls

This is a fixed version of the Sheep Girl model from the mod. I corrected the model data, so her coat no longer looks broken, and the baby form can now stand properly on the ground instead of floating. This only includes the modified JEM data for the Sheep Girl; If you want to other girls, you need to use it with the original resource pack.
