Alpha v0.21.1

This update fixes a pretty crucial bug with upscaling images with transparency with PyTorch models.

Important note: I forgot to mention last update to make sure you have the latest Nvidia drivers after you update PyTorch. If your drivers haven't been updated in over a year, PyTorch upscaling might start not working or being extremely slow.
