We add an entire class like we do for parsing other codec initialization formats; it's currently not doing any parsing though (... initialization data is really simple for AV1 though: just the entire contents of the box).
For testing, we add the sample file, having been re-encoded with ffmpeg (and we also happen to have another av1 file, too).

This provides better compatibility with MediaExtractor, which does read these fields; we also need them for being able to mux file contents into another mp4 file.
Also, there is a minor refactor included so that we have an actual type for esds box contents instead of a pair.

For when a track is both encrypted and has supplemental data, the sample size will be equal to `block sample size - encryption data size`.

This is a breaking change if the annotation itself is in use in Kotlin
code. It's judged that the IntDefs in this commit are unlikely to be
referred to often in Kotlin code. This is because they're either:
- Related to esoteric parts of the library, or
- In a common part of the library but only returned from methods (and
never passed to callback methods).
A follow-up change will fix the positions of existing usages to match
this new config.

This only changes IntDefs that cannot be used by apps because they're
either private or package-private.

this new config.

The longer list of targets is only necessary for backwards
compatibility with existing Kotlin code that will stop compiling
if the position of the annotation becomes 'wrong' by marking it only
TYPE_USE. Since none of these IntDefs have been released (except in
media3 alpha1) we don't need to maintain this compatibility.
Also add a comment to all the places that *do* need the longer list of
targets, in order to explain why it's there and discourage copy-pasting
when defining new IntDefs in future.
Also fix some single-element arrays to remove the array notation.

Populate ICY headers into MediaMetadata so that they can
propagate to the app via AnalyticsListener#onMediaMetadataChanged().
This change copies IcyHeaders.name into MediaMetadata.description
and IcyHeaders.genre into MediaMetadata.genre.
Note: MediaItem.metadata maintain their precedence and overwrite any
ICY headers parsed.

The presentation time in fMP4 is calculated by adding and subtracting
3 values. All 3 values are currently converted to microseconds first
before the calculation, leading to rounding errors. The rounding errors
can be avoided by doing the conversion to microseconds as the last step.
For example:
In timescale 96000: 8008+8008-16016 = 0
Rounding to us first: 83416+83416-166833=-1

Test file produced with:
$ MP4Box -add "sample.mp4#video:colr=nclc,1,1,1" -new sample_18byte_nclx_colr.mp4
And then manually changing the `nclc` bytes to `nclx`.
This produces an 18-byte `colr` box with type `nclx`. The bitstream of
this file does not contain HDR content, so the file itself is invalid
for playback with a real decoder, but adding the box is enough to test
the extractor change in this commit.
(aside: MP4Box will let you pass `nclx`, but it requires 4 parameters, i.e. it
requires the full_range_flag to be set, resulting in a valid 19-byte colr box)
