Checkpoint in ongoing research

This is not a release. I am still trying to improve this. but it is currently better than sd or sdxl vae. As it SHOULD be for f8c32 instead of f8c4

But it should be better

See https://github.com/ppbrown/sd15_vae-f8c32 for tools I used to train it.

Results from utility "calculate_loss.py" (Smaller is better)
