WebVTT cues without payload may not carry meaningful information, but it
is allowed by WebVTT specification [1]. It could also be useful
sometimes, e.g. to signal the time progression in live case.
Fixes#433.

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.

When originally implementing the webvtt parser, there was a
misunderstanding in what the BOM was suppose to be
(https://en.wikipedia.org/wiki/Byte_order_mark). This corrects the
misunderstanding.

To ensure that we can parse content with style and region blocks,
this change updates the parser to skip those blocks so that we
can still parse the cues from a file.
Full style and region support will be added later this year.
Issue #380

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.

Instead of having multiple char readers, one for strings and
one for files, just have one for files and use memory files
when testing.

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.
