add ProRes 4444 XQ

Version 3.0.0 works fine for ProRes 4444 (codec_tag_string = ap4h), but not for ProRes 4444 XQ (codec_tag_string = ap4x) which gives an error "No description for this codec".

Yes, on ffplay and mpv it works fine.

Yes, a file – with an empty alpha – is now available at https://avpres.net/Dufay_ProRes4444HQ.mov (MD5 = 1b308c6ef8b354f9e71243744b7b53a3).
