qtdemux: Add support for DNxHR

Browse Source 
Apart from the fourcc it works the same as DNxHD and can be distinguished from
the beginning of each frame header.

ffmpeg uses the same codec ID for DNxHD and DNxHR so we use the same caps with
just an additional, optional profile field for the DNxHR profile.
