Synchronize video frames with an external mapping from a file.
Follows up on the idea in
https://lists.ffmpeg.org/pipermail/ffmpeg-devel/2023-January/305986.html
implemented as a filter.
Not storing the frame map in a probably huge string but buffering
piece-wise. Using a fixed format string.

The {br}/{abr} directives are not limited to post-encoding, they can

Currently, the logic inside the FF_FILTER_FORMATS_QUERY_FUNC branch
prevents this code from running in the event that we have a filter with
a single video input and a single audio output, as the resulting audio
output link will not have its channel counts / samplerates correctly

I looked at how other parts of the codebase check for errors on strtol and
implemented it that way (iec61883, filter_units_bsf, etc).
As for checking if the string value is larger/smaller than a long, i don't
