Oliver Woodman bf77f3b289 Simplify subtitle parsing.
- Currently all subtitles we parse contain timestamps relative to the sample
  timestamp, however we add the sample timestamp in inconsistent ways (sometimes
  in the Subtitle, sometimes in the SubtitleParser). This change converges on
  a single approach. It also paves the way for passing absolute offsets to use
  instead, and being able to apply them in a consistent way in a single place
  (PlayableSubtitle). This functionality will be required for ISO 14496-30 TTML
  embedded subtitles.
