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)

- Fix use of getTimestampOffsetUs in TsExtractor where
getFirstSampleTimestampUs should have been used.
- Don't reset TimestampAdjuster if it's in no-offset mode.
- Improve comment clarity

First intention to support parsing MPEG-H 3D Audio in ExoPlayer is to
take advantage of parsing capability from MediaParser API in AOSP.
Just with this change ExoPlayer does't support decoding MPEG-H 3D Audio
but can support decoding either by adding decoder with an extension or
by using Android OS which has decoder capability with MediaCodec API.
- Fix comparison between a byte and 0xFF to avoid conversion of 0xFF to
byte and to int again (due to numeric promotion).
- Fix addition of int and byte with most significant bit set. The byte
was incorrectly promoted to an int negative value.

This was reported for SSA/ASS in PR #8265, but it seems to me the
SubRip part of the Matroska spec is similarly loose, so this change
handles null-terminated strings in both.

This will mean the track is automatically used when running in a
playback test.
Command used to change the flag:
```
$ mkvpropedit sample_with_srt.mkv --edit track:3 --set flag-default=1

When I moved ParsableByteArray#data behind a getter I replaced some
assignments with calls to reset(byte[]):
ce2e6e2fd6
reset(byte[]) deliberately sets `limit` to `data.length`, in order to
handle cases that were reassigning `data` but not updating `limit`.
However OggPacket was already using `limit` to track where to write
'new' data into the array, so changing `limit` to `data.length` caused
us to try and write new data beyond the end of the array.
I looked at other uses of reset(byte[]) in ce2e6e2fd6
and condluded the only other usage in MatroskaExtractor is legit and
shouldn't be updated like this (because MatroskaExtractor previously
*wasn't* correctly updating/maintaining `limit`).

This allows us to more easily create different dumps derived from the
same assets.
This moves media/source files from `assets/` to `assets/media/` and
dump files from `assets/` to `assets/extractordumps/` and
`assets/audiosinkdumps/` as appropriate. I intend to add
`assets/playbackdumps/` in a future CL.
