Try autodetecting QooCam EGO side-by-side DNG photos

QooCam EGO camera stores photos in parallel format within DNG files. It would be helpful to try auto-detecting stereoscopic format of these photos, although it seems that they lack information in any standardized form. Instead, it seems that software coming with the camera detects this information from 'User Comment' section:

Note that it seems FFmpeg 7.1 is unable to apply automatic color-conversion from DNG format, so usability of supporting DNG by sView is currently under the question.
