IMF Demuxer: Pull starting timecode from CPL

Description

The IMF demuxer does not currently return the starting timecode declared in the CPL.

This should be retrieved from the CPL and passed downstream to muxers that support it like MOV and MXF.

How to reproduce:

% ffmpeg -f imf -i input_cpl.xml... output

See proposed patch at ​https://github.com/sandflow/ffmpeg-imf/pull/100

The patch sets the starting timecode based on the content of the CompositionPlaylist/CompositionTimecode element of the Composition Playlist, unless the starting timecode has already been set through other means, e.g. using the -timecode command line entry.
