Add SDXL Support

[brianjking]

Hello,

Is it possible to add SD XL support?

I'd love a colab notebook for this as well.

Thanks!

To add SDXL support, all you have to do is create a new extension with the correct SDXL logic (loading from HF diffusers, etc.). You could parameterize num_inference_steps, for example, to delegate decisions to the user of the extension.

If anyone gets to making one before me, please leave a PR!
