jpegrecoverymap: add initial recovery map calculations.

This change adds the starting point for generating and applying the
recovery map. A follow-up change will add more robust tests for this
update (eg. unit testing color conversions).

There are a few other known TODOs remaining for these map operations:
  * Clean up handling around hdr_ratio (ie. utilizing XMP)
  * Add color space information for inputs and utilize it for ICC data
  * Add handling for PQ encode/decode
