Use the "speedy" version of the inpainting model

[zeke]

@daanelson recently published a faster version of the inpainting model: https://replicate.com/daanelson/speedy-stable-diffusion-inpainting

Assuming the API is compatible with https://replicate.com/stability-ai/stable-diffusion-inpainting, maybe we should give it a go!

Should be totally compatible! Give it a shot.

I took speedy for a spin but that model is not being kept warm, so it was actually slower due to a cold boot. Hmm...
