Read color profile from QImage
Look at #7 (closed)
Qt 5.14 introduced new class QColorSpace. Lot of Qt supported image formats set color profile via this class.
gwenview already reads color profiles directly from JPG and PNG files and from some other formats via Exiv2.
This patch enables profile color loading for other formats, it will help to correctly display AVIF, JXL and HEIF/HEIC especially.
