Rebase the first packet's timestamp onto the start of the segment list regardless of playlist type, and report it as start_time. Previously only EVENT playlists did this and live streams took start_time from the first loaded segment at the live edge. Which is not correct as some servers provide very deep (hours even) time shift in live playlist. The evicted segments are already tracked by EXT-X-MEDIA-SEQUENCE. This allows us to use all available segments, not only the future ones on live playlist. Also prefer PTS over DTS, as EXTINF durations and start_time are presentation time.
