The initial performance figures aren't looking too good for Anim. This could benefit from some benchmarking/profiling.

Anim -> AnimData: 726.5µs

The bits.extend seems to copy one bit at a time. There should be some way to avoid multiple allocations per compressed buffer and potentially pool some of the bit sets together.

Allocating a single buffer and more intelligently setting the elements gives a roughly 4.5x speedup.
