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).

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.

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