In addition to the MediaSample handling of the MediaParser, this now
adds callbacks for TextSample. This allows reading text streams from
the media files.

The right way to detect the presence of a keyframe in a BlockGroup

For WebM contents, it is possible that we may receive some NewSampleEvent
before receiving ParserInitEvent. This is because init event is fired
after analyzing a video block which could come after an audio block.
Also modified Flush() function to return a bool to indicate whether the
the flush is successful and whether the samples are handled correctly.
And added macro to ensure Flush() and Parse() results are handled.

- dts was not set earlier, although for WebM, we could assume that
dts is the same as pts.
- Calculate block duration with the difference with the next block
if duration is not encoded, even if track default_duration is set.
- Use track default_duration as a duration estimate for the last
block.
- This also removes opus duration computation from encoded data.
