Implement Animation Compression

Browse Source 
Roughly based on https://github.com/godotengine/godot-proposals/issues/3375 (used format is slightly different).

* Implement bitwidth based animation compression (see animation.h for format).
* Can compress imported animations up to 10 times.
* Compression format opens the door to streaming.
* Works transparently (happens all inside animation.h)
