Injecting metadata from file MISP

[Fran Raga]

Finally I made a parser to use the videos of a DJI without creating an
MISB, and create klv packets for after demux (I do not know how create MISB)

It's pure python

https://github.com/All4Gis/QGISFMV/blob/dev/code/player/QgsMultiplexor.py

I hope that it would be useful to someone
