NijiGimpy V1

Known Issues: Images need upscaling, especially with the eyes. Not sure how to fix that right now, probably going to train a V2 in the near future after pruning training data for whatever makes some features come out wonky.

Also working on making my own Niji-esque checkpoint because we don't have a decent one on civ and the folks on Tensor are rather stingy when it comes to sharing AI resources but I digress.
