Add ControlNet Support

[saddam213]

Add ControlNet support to OnnxStack.StabeDiffusion

This has need a highly requested feature, so time to get it underway.

Implementation wise it seems straight forward, we just have an extra model file, this being the control model, depth, edge etc

We will run the Control model first then feed the result into the Unet of the defined stable diffusion model

Figuring out the inputs/outputs of the ControlNet model and how to pass that model down as an input are the main bits to sort out, the rest should be fairly easy.

Basic Outline

• Pipeline - Add ControlNet pipeline
• Diffusers - Image, Inpaint, Video
• ModelSet - Pass a "Control ModelSet" with the main ModelSet somehow? submodule time?
• Feature Extractors - Canny, HardEdge, Depth, OpenPose
• Basic UI integration

Success, ControlNet prototype is starting to spit out results :)

Long way to go, but a good start... :)

ImageService to process input images is complete, we can now process Canny, HardEdge(HED) and Depth inputs
