Support additional Stable Diffusion modes

[zolrath]

As discussed in #111, Stable Diffusion supports a number of different modes.

Currently, only text-to-image is supported but the other modes are considered in-scope, verified by seanmor5.

Currently Supported

• [x] text-to-image
• [x] ControlNet (#359)

Currently Unsupported

• [ ] Stable Diffusion XL
• [ ] Stable Diffusion XL - Lightning
• [ ] image-to-image
• [ ] depth-to-image
• [ ] inpainting
• [ ] upscaling

As #111 was closed when the general support for Stable Diffusion 2 was added, it seemed appropriate to track these separately.

Looks like there's great work being done in #359 to add ControlNet to Stable Diffusion thanks to the work of @joelpaulkoch so this list is on it's way to being shorter. ControlNet adds an incredible amount of use cases to Stable Diffusion so it's great to see!
