Local adjustments - Cam16 and Log encoding improvments

Hello

I made various improvements to this PR (lacam16n branch), both in terms of:

  • GUI by preventing (hopefully) bad behavior in certain situations
  • for “Pre-ciecam” by adding some features (shift x and shift y in CIE xy diagram)
  • by improving the behavior in the case of images with very high dynamics, both for “Log encoding” and “Cam16” (in this case the result is a little different). Note I added 2 controls - White and black distribution"
  • ensuring compatibility with “Abstract profiles”
  • others small changes.

Example with “Log encoding” in “Local adjustments”
