This is required before we can move CEA-6/708 parsing from the rendering
side of the sample queue to the extraction side.
This re-ordering is needed for video encodings with different decoder
and presentation orders, because the CEA-6/708 data is attached to each
frame and needs to be processed in presentation order instead of decode
order. This change re-orders frames within a group-of-pictures, but also
takes advantage of `maxNumReorderFrames/Pics` values to cap the size of
the re-ordering queue, allowing caption data to be released 'earlier'
than the end of a GoP.
Annex D of the CEA-708 spec (which also applies for CEA-608 embedded in
SEI messages), makes the need to re-order from decode to presentation
order clear.
