ibaker a783d704b2 Add duration to text/x-exoplayer-cues binary format
This plumbs a duration through `SampleQueue` which will make it easier
to handle transcoding muxed subtitles from e.g. SubRip to
`text/x-exoplayer-cues`.

This change is a no-op to the end-to-end behaviour of ExoPlayer because
currently we only support parsing sideloaded subtitles before
`SampleQueue`, and by adding the duration we don't affect the cues that
are ultimately output by `Player.Listener.onCues` (as shown by no change
to the golden files for `WebvttPlaybackTest` in this commit).

I considered making `CuesWithStartTimeAndDuration` implement
`Bundleable` (and deleting `CueEncoder/Decoder`) but decided against
it because we are deliberately not encoding `startTimeUs` (since that's
encoded as the sample time in `SampleQueue`). I also considered
introducing another type that only has `List<Cue>` and `durationUs`
fields, but it didn't seem necessary, since we want `startTimeUs`
everywhere else (except inside `SampleQueue`).

ExoPlayer module

This module provides ExoPlayer, the Player implementation for local media playback on Android.

Getting the module

The easiest way to get the module is to add it as a gradle dependency:

implementation 'androidx.media3:media3-exoplayer:1.X.X'

where 1.X.X is the version, which must match the version of the other media modules being used.

Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.
