--------------
x Fix regression on Windows with directory names beginning by n or r.

+ MXF: detection and parsing of ProRes (SMPTE RDD 44)
+ MXF: HDR metadata support
+ AVC: add consumer camera recording date/time

+ MediaInfo JSON output
x colour description: trying (again!) to have more coherent labeling
x AAC: SBR parsing issue with 3+ channel streams, with sometimes false-positive PS detection
x DPX: some elements in trace were wrongly displayed (wrong endianess)
