This implements a
chroma
struct in dev (like a proxy) holding all required and available white balance data for the current image (D65, as_shot and currently used) allowing runtimea) check - are we using D65?
b) access of modules to the other coeffs for improved results c) easier and safe checks for chroma correction related trouble messages
@TurboGit for you as this might be easier to review.
It's a stripped down version of #15461, this should not change anything in current master behaviour except safer message generation and keeping data in the dev chroma struct. The other pr could be rebased on this after possibly getting merged.
Fixes #14518
