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.
