Pre1.21 mace and wind charges

https://github.com/ViaVersion/ViaBackwards/commit/9ca523620d31999f540847187ddc1e319b5798ee

Adding this pack when wind charges get fixed to become shulker bullets (look at github commit)

Added a custom entity model for the llama spit to be changed into a wind charge. Couldn't seem to figure out if there was special nbt data on the llama spit in viabackwards, so I made all of them into wind charges. Kind of funny when a llama hits you with a wind charge though.

If you want the wind charge to look like a wind charge, use Entity Model Features
