NijiGimpy V3

This is going to be my V3 on this journey to making a Niji lora akin to the models one might find on other sites, except I want it to be free for anyone and everyone to download and use. There are still issues I have with making eyes, but I'm working on it, it'll probably be another week or two before I can train something again. I'm just in the middle of pruning images as well as adding images to the dataset until I find something I'm comfortable with. The good news is that I've got a V1 of a checkpoint working, it's not perfect, it's a little soft, the lighting isn't as dramatic as I'd like it, but a starting point is better than nothing.

This is what I've been using as a default, a better sampler will be dpmpp2m and karras as a scheduler but I like to work in a parameter people can use online. Feel free to tweak, tune, and merge so long as you don't paywall a stupid lora.
