ControlNet support

[zolrath]

Hello!
Amazing project! Hats off, this work could really allow a lot of AI projects to provide value and entertainment to users without costing an arm and a leg.

I've been prototyping a user generated content system for the last month or so and a core requirement for it is ControlNet support.

This isn't necessarily a request for support to be added (though that would be amazing) but is also checking to see if TVM/Unity and this project are capable of having that support added to it.

I noticed the lack of img2img as well and wasn't sure if this was out of grasp for the moment.

Thanks again, really excited about this project!
