avformat/imfdec: use CPL start timecode if available 
The IMF CPL contains an optional timecode start address. This patch reads the
latter, if present, into the context's timecode metadata parameter.
This addresses https://trac.ffmpeg.org/ticket/9842.

avformat/imf: add support for input seeking 
The IMF demuxer did not implement AVInputFormat::read_seek2(), resulting in
inefficient input seeking.

Addresses https://trac.ffmpeg.org/ticket/9648

Byte- and frame-seeking are not supported.

avformat/imf: fix packet pts, dts and muxing 
The IMF demuxer does not set the DTS and PTS of packets accurately in all
scenarios. Moreover, audio packets are not trimmed when they exceed the
duration of the underlying resource.

imf-cpl-with-repeat FATE ref file is regenerated.

IMF CPLs can reference thousands of files, which can result in system limits
