## @file
## @brief Extract embedded jpegs from a raw file
##
## Use exiftool if it detects a higher number of preview
## images, otherwise use exiv2 if available
## - exiv2 does not see the largest preview image in a .cr3 file.
##
## Note that exiftool is noticeably slower than exiv2
##
## - Display a list of the embedded files
## - Extract the selected image to a tmp folder
## - Rotate image if exif data is available
## - If jpgicc is installed, correct for currently selected rendering intent
## - Store in a new file
## - Set Geeqie focus to the newly generated image
