This change also includes mapping the numeric ID3v1 codes to their
string equivalents before setting them into `MediaMetadata`. This
mapping already existed, but it was previously only used when parsing
MP4 `gnre` atoms.

This change adds a 'free-form' text genre to the existing
`bear-id3.mp3` sample, and adds a new sample with a 'numeric' genre ([9
is Metal](https://mutagen-specs.readthedocs.io/en/latest/id3/id3v2.4.0-frames.html#appendix-a-genre-list-from-id3v1)).
The samples were modified with:
```shell
$ id3edit --set-genre "Gorpcore" bear-id3.mp3
$ id3edit --set-genre "9" bear-id3-numeric-genre.mp3
```
Reading the numeric genre with `exiftool` shows the mapping back to
'Metal':
```
$ exiftool bear-id3-numeric-genre.mp3 | grep Genre
Genre : Metal
```
The playback dumps don't contain the genre because it's not yet
propagated to `MediaMetadata.genre`. That is done in a follow-up
change.

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.

It's a bit arguable whether the `Subtitle` implementation supports
zero-duration events, since `getEventTimeCount` is documented as
effectively "the number of times the cues returns by `getCues(long)`
changes", and zero-duration events violate that. However, the current
`WebvttSubtitle` impl **does** produce zero-duration events, so it
seems safer to handle them gracefully here and then, as a possible
follow-up, fix the `WebvttSubtitle` impl (or remove it completely).

When applying edit lists, we need to output the last partial samples
to have all the necessary data needed for rendering.
The only case where we can omit the sample is for zero duration
audio data that has no additional information.
The current comment and variable name doesn't make this very clear
and this change improves the naming and the comment.

The track id must be the index in the list of published tracks
as it's used as such elsewhere. This is currently not true if we
skip an empty track as all subsequent tracks get a wrong or even
invalid id.

The current implementation of `JpegMotionPhotoExtractor.sniff` returns
`true` for any image with Exif data (not just motion photos). Improving
this is tracked by b/324033919. In the meantime, when we 'extract' a
non-motion photo with `JpegMotionPhotoExtractor`, the result is
currently a single empty image track and no video track (since there's
no video, since this isn't a motion photo). This 'empty' image track
is usually used to transmit metadata about the video parts of the
image file (in the form of `MotionPhotoMetadata`), but this metadata is
also (understandably) absent for non-motion photos. Therefore there's
no need to emit this image track at all, and it's clearer to emit no
tracks at all when extracting a non-motion photo using
`JpegMotionPhotoExtractor`.
This change also removes a `TODO` that is misplaced, since there's no
image bytes being emitted here (and never was).
PiperOrigin-RevId: 604688053
These are often the same for image tracks, since we usually drop the
whole image file (both the container and actual encoded image bytes)
into a single sample, but there are cases where we emit a track with
`containerMimeType=image/jpeg` but **no** samples (from
`JpegMotionPhotoExtractor`, to carry some metadata about the image +
video byte offsets).
It's therefore more correct to implement the `supportsFormat` check
based on `sampleMimeType`, so that these 'empty' image tracks are not
considered 'supported' by `ImageRenderer`.

Due to the re-ordering of packets done in `CeaDecoder`, there's no way
to use the current implementation to correctly parse these subtitle
formats during extraction (the `SubtitleParser` interface), so we have
to keep the `SubtitleDecoder` implementations.

- Added back parsing of scheme data for version 1 as it's technically
allowed by the spec.
- Made constructor of PsshAtom private to only publish the data class
and not the constructor.
- Formatting and Javadoc adjustments
- Additional tests
Many usages are needed to support other deprecations and some
can be replaced by the recommended direct alternative.
Also replace links to deprecated/redirected dev site

It's likely that we will merge these back into their `XXXDecoder`
implementations, but this smaller change allows us to avoid including
these public symbols in the upcoming release.
