feat: To give Jan the ability to process and produce image files

[davidawad]

Problem
This perhaps is a bit too large of a problem for Jan alone to solve, but it would be amazing to have a way to drop images into Jan with a prompt to ask for image generation and modification.

This falls in line with this epic lining up Jan with chatGPT.

Success Criteria
I suppose a few things would have to occur.

• Some standard (similar to GGUF in the LLM context) would have to be settled on for image generating deep neural nets
• an image interface would need to be built (basics like pasting from clipboard would have to be worked out
• the UI will need to allow you to pick and select your operation type (image, text, video, etc.).
  • (this can be inferred automatically in some use cases as well depending on whether a user has pasted an image or something like that)
• some resolution settings would have to be added
