Instead of always tracking segments with an index, this change makes a struct
that will act as the segment and track which segments are in it. Each
segment will store all the samples in the order they were given, it will
avoid any sorting.

According to the HLS+WebVTT spec, if there is no text in a segment
a webvtt file with no cues can be added to the manifest. By outputting
empty segments it allows the accumulated duration in the Master Playlist
to better represent the duration of the text stream.

To better align with the Chunking Handler, the Text Segmenter
now outputs the SegmentInfo at the end of the segment rather
than the start.

This change creates the webvtt segmenter which will be used for
segmented text webvtt for HLS. It takes a stream of text samples
and injects segment info messages based on the segment duration.
It is possible for samples to extend between segments, if so the
sample will appear twice (once in each segment).
