[P] Training anime diffusion model from scratch with limited compute

[Blog post](https://medium.com/@enryu9000/anifusion-diffusion-models-for-anime-pictures-138cf1af2cbe)

This uses a [nice dataset](https://www.gwern.net/Danbooru2021) by /u/gwern, and trains a decent latent-diffusion-based model from scratch, with several orders of magnitude less compute than Stable Diffusion (although anime-only, but it is better than Stable Diffusion on anime pictures).

FWIW, a [self-hosted demo](https://9a8b9984a23d9302.gradio.app/) (I tried to restrict it to produce only safe samples)

It runs via Gradio proxy, so it is flaky and unstable at times, but works after some retries. I'll keep it running for the next several days.
