TTML Return format of the Time values #2065

For timed text files i.e. SMPTE-TT, IMSC, is it possible to check the format of the timecode values. TTML allows several timebase formats but we only allow specific ones.

Make sure they are all the same. No mismatch
Make sure they are either one of hh:mm:ss:ff or hh:mm:ss.sss.

As requested logging this ticket here for MediaInfo and will use in Media Conch

We would list the time formats in a specific field (hidden by default in MediaInfo but usable in MediaConch) and you would be able to check with MediaConch with a rule "if field is HH:MM:SS:FF or field is "HH:MM:SS.mmm".
