Add Prompt Suggestions with CLIP Interrogator integration.

[swcrazyfan]

I've been experimenting with using CLIP Interrogator to come up with prompts to mimic specific images, and it's worked surprisingly well to give me a head start!

Would it be difficult to add something like this in a tab? Would be great to not have to run in a separate Colab instance.
