Jacob Trimble 1f21cc78cd Add style support for cue fragments.
Now text cues are composed of nested fragments that can be individually
styled.  This allows portions of the cue to be bold, etc.  The
WebVTT parser doesn't parse the inputs, but the original tags are
preserved in WebVTT output.  The WebVTT output will add tags if the
style elements are present in the cue object.

Jacob Trimble 414f4589c8 Parse TextSettings from WebVTT.
Now the Cue settings are a generic object that is parsed in WebVTT.
This will allow setting the settings in different parsers without having
to use WebVTT-specifics.

Jacob Trimble b2220eb0c6 Add text fragment and setting types.
This sets the groundwork for more generic text cues by having a more
generic object for the settings and the body.  This also changes the
TextSample to be immutable and accepts the fields in the constructor
instead of using setters.

Changed Text Sample to use int64_t so that it will use the same
type for time as Media Sample.

Aaron Vaage c88fe54553 WebVTT Output
This change introduces handlers to output WebVtt text files. There is
only one output but there is a common base to support others.

WebVttOutputHandler which handles all communication with other handlers
and WebVttSegmentedOutputHandler is responsible for listening for events
and choosing when and where to write cues and headers.

done in controlled setting.

Aaron Vaage 2d2825290c Added TextSample
Added a text sample type that can be passed between media handlers.
This will allow text samples to safely be moved between media
handlers before converting to their final format.
