FR: multiple results per image when using postprocessors

[Efreak]

When using hires-fix and postprocessors, it's far more efficient to have the same worker do everything, however if it turns out poorly you have no idea if it's the fault of the postprocessor or the original generation.

It would be nice if there was a flag I could use to have the worker return all the intermediate images in a given request. I'm more than happy to pay a kudos tax to both the worker and the Horde for returning the images at each processing step:

• background removal
• face-fixer
• upscale
• hires-fix (unsure if this is possible)

I brought this up last month and was told I should make a GitHub issue.
