Lefties (Golden Shiny Mob Variants)

Hello, here is my take on a shiny mobs pack, Lefties!
-------

Ever have a mob variant pack, but the mobs lose their skins when you rejoin the world?

This fixes that by only applying the golden skin to mobs that are left handed.
-------

Yeah, you read that correctly. Every mob in the game, not just mobs that can hold items in their hands, has a chance to be left handed by default. (Strange, isn't it?)

Since it doesn't rely on something that can change, like what biome the mob is in, you can trust that they'll stay golden!

To make sure the pack works, go into a world with commands enabled and run this command:

/summon minecraft:zombie ~ ~ ~ {LeftHanded:1}
-------

A few minor changes have been put in as well:
- Allays that are on cooldown for duplication turn amethyst purple. Don't worry, they'll get their gold skin back when the cooldown ends
- Creepers turn blue when charged
- Creepers also turn red and smile when ignited by a player
-------

An important thing of note:

You need to use either Entity Texture Features or Optifine for this pack to function.

This was developed in ETF, so I can't guarantee that 100% of the features will work with Optifine.
