KongQun Yang f49b89280c Support STYLE and REGION in WebVTT
Note that STYLE and REGION are not supported in mp4 container due to
spec limitation as 14496-30:2014 does not specify a way to signal
styles/regions inside mp4.

Closes #344.

Aaron Vaage 7dd80884c3 WebVtt Ignore Zero Duration Cues
We have an assert that ensures that the end time is greater than
the start time for any cue. However we never checked that cues
had a non-zero duration when parsing them.

We will throw away cues with a duration of zero (and print a
warning message) as they are not spec compliant.

Closes: #335

Aaron Vaage 9e7b5c1ca9 Change CharReader to FileReader
Instead of having multiple char readers, one for strings and
one for files, just have one for files and use memory files
when testing.

Aaron Vaage 4dcfe413f5 WebVTT Parser
Took the WebVTT Media Parser and created the WebVTT Parser
that will take in a file and output a stream of cues that
will later be passed to another Media Handler that takes in
cues and chunks them.
