ibaker d76ee54ca6 Add two MP4 samples with metadata
The first has a string genre, and various other values set, generated
from `sample.mp4` with the command below [1].

The second has a numeric genre, to test `gnre` atom parsing. This
parsing is currently broken, the fix is in a follow-up change. This
file was also generated from `sample.mp4` with the command below [2].

This change also includes `CommentFrame.text` in its `toString`
representation, otherwise there's no difference between e.g. different
levels of `ITUNESADVISORY` in the extractor dump files.

Issue: androidx/media#1305

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.
