Deflick.mo: Not handling file naming for aRGB.
Created originally on Bitbucket by WalterSchulz (Walter Schulz)
If color space is set to Adobe RGB (thus using _MG_xxxx.CR2 naming) sidecar files containing names according to sRGB (IMG_xxxx.CR2). Naming for sidecar files is done according to sRGB naming conventions, too: IMG_xxxx.UFR.
