softworkz fcc50c41ce avformat/hls demuxer: Add WebVTT subtitle support 
This add support for WebVTT subtitles in HLS streams.
Just like for separate audio streams, it supports all available
WebVTT streams in all renditions.
No new options are added, it just works and provides subtitles streams
like any other demuxer.
The code prevents downloading subtitle segments which are farther
in the future than the main segments, to avoid loading hundreds
of subtitle segments in advance.
