Subtitles: Allow transitions between ATSC and SCTE captions.
In changeset d526385aa4c1466b064e9544cdb663f357007e35 (refs #9829),
code was added such that the first time ATSC caption data is seen, any
future SCTE caption data is explicitly ignored.  This was to deal with
broadcasts containing duplicate caption data.

This policy causes problems when the recording switches back and forth
between the two sources of caption data, such as when the broadcaster
splices in commercials.

The updated solution continues to favor ATSC data, but allows a switch
back to SCTE after SCTE data is seen 10 times in a row (a somewhat
arbitrarily chosen number) without intervening ATSC data.

Refs #12054.

(cherry picked from commit 68bd03ffe5b7bb6456519639caac77486ea0941c)
