Cue interval tree (Dash-Industry-Forum#4812)

* feat: create IntervalTree for O(log n) lookup of cues within an interval

* feat: keep all cues in an IntervalTree and only a small range in the native TextTrack

* refactor: rename IntervalTree to CueIntervalTree

* refactor: make _onPlaybackSeeked more consistent with _onPlaybackTimeUpdated

* refactor: avoid checking same condition multiple times

* fix: hopefully fix the TypeError  on functional test for forced subtitles on MacOSX Firefox 142

* refactor: delete workaround for a bug from pre-Chromium MS Edge

* fix: restore cue extension logic
