Animated textures support for optifine models

[aurora-1-2-3]

Detailed description of your suggestion

Animated textures are possible but Blockbench doesn't support it

Pretty docs: https://optifine.readthedocs.io/custom_animations.html

Github docs: https://github.com/sp614x/optifine/blob/master/OptiFineDoc/doc/custom_animations.txt

Example: (in-game)

Issues:

1. When you try to reframe the animations tiles through the flipbook in the Optifine format, it reverts its self to 1

Example: I reframe the texture to 16 different frames

I opened the flipbook again and it reverted itself to 1

2. Texture glitching?

When you try to apply that animated texture to the element, this happens
