[FEATURE REQUEST]: Index map of all faces in an image

[alessandroperilli]

Feature description

Occasionally, I have to swap a face in an image with many faces. It's always a time consuming guessing game (partially related to #149). It would be really cool if the node had an optional output (to be connected to a Preview Image node) showing the index number for each face appearing in the image. So, at least, one would run the node once in map mode to see where each face is, and then do a proper face swap.

Or maybe have a dedicated node for this particular job.

I realise that this is a niche use case and it might not be worth the effort. Thanks for considering it.

or be able to input a mask or SEGS.

@Gourieff any updates on this? Still haven't found a good workaround, especially for video
