Stable Diffusion misc code

Miscellaneous code for Stable Diffusion stuff.

Textual Inversion Colab Notebook

Changes to the original:

• Allow custom captioning
• Zip file of all embeddings (and a handy download button)
• Little QoL things like custom embed filenames etc

Future modifications to allow for multiple learning rates (if possible)

This version does not automatically re-size to 512x512 nor convert to JPEG. So train whatever size you'd like (I'd suggest 512x512).

Note that the Textual Inversion notebook is originally from Hugging Face here: https://github.com/huggingface/notebooks/blob/main/diffusers/sd_textual_inversion_training.ipynb which is licensed under Apache 2.0. and originally copyrighted by them.
