Add "Color Compressor" feature to Face Refinement tool

I often find myself having to color-correct for poor on-set makeup decisions, where the talent ends up having splotchy areas of non-uniform color. Right now I use either tracked HSL Qualifiers or HSL Curves to fix issues like this, but I would love to see the Face Refinement tool to inherit some of the capabilities of the "Color Compressor" tool, where it would even out these types of color disparities without having to pull a key on the face first.

I would love for you to be able to correct color differences in the Side Lighting.

Or use the Face Refinement data elsewhere.
