fpreadjpeg: CorrectCMYK()
https://gitlab.com/freepascal.org/fpc/source/-/blob/main/packages/fcl-image/src/fpreadjpeg.pas
Bug: CorrectCMYK() does not convert from CMYK to RGB.\
The wrong colors can be seen in TImage showing the file from cmykjpg.zip at: https://gitlab.com/freepascal.org/fpc/source/-/issues/21916.
Solution: Common default conversion.\
This is the simplest solution, but is intended to resolve this report.\
(To prevent possible endless waiting for complex alternatives (using color profiles))\
