Aaron Vaage 5f072e3b08 Start Segments At First Sample in Text Chunker
We always assumed that text stream started at zero in the text chunker.
This meant that if the text stream started later than zero (like in a
live stream) we would generate a lot of empty segments.

Instead the text chunker will assume that segments should be adjusted
to align with multiple of segment duration. The text chunker will assume
that an earlier component in the pipeline (i.e. text padder) will ensure
that the first sample has the time that we want to start segments at
(even it needs to add an empty sample).

Issue #416

Aaron Vaage fbc4952e21 Updated StreamData Matchers to Use Matchers
Updated all the stream data matcher we use in our unit tests
to allow us to use matchers in them. We are now able to use "_"
to ignore specific parameters.

With this we were able to replace the different version of
matchers for each stream data type with a single instance for
each type.

Includes updates to printing strings to the listener. Strings
now go through a "pretty" function to help make it easier to
read them in the output.

Aaron Vaage dbce84f3ea Remove Time Scale Assumptions From Text Chunker
Before, the text chunker would assume that all text streams were in
MS, which is not a safe assumption to make.

This changes it to take the time scale from StreamInfo and work
natively with scaled time units.

This required updating the tests. While doing so the tests were
rewritten with the goal to make them easier to read.

Closes: #399

Aaron Vaage 30b189cb99 Make Test Util 'GetTextStreamInfo' require Time Scale
Make the text stream info factory method in media_handler_test_base
require the caller to specify the time scale.

Aaron Vaage a11cbf93a7 Handle CueEvent in TextChunker
Updated TextChunker to handle incoming CueEvents. Connecting the
text chunker with the cue alignment handler will happen in a later
CL.

Aaron Vaage 8f565bf388 Change Text Sample to Use int64_t
Changed Text Sample to use int64_t so that it will use the same
type for time as Media Sample.

Aaron Vaage 56caecd073 Rename WebVttSegmenter To TextChunker
Renamed the webvtt segmenter to text chunker as there is nothing
webvtt specific in the code.
