Also adds first frame rendered test for playing back compositions.
- This test checks the output pixels using an `ImageReader` to retrieve the
output bitmap

Part of a two stage change to remove the conversion to linear colors in the SDR effects pipeline by default. Changes the boolean to an intdef, introducing a third option that gets all sdr input into the same colorspace.
This is a planned API breaking change, but this change should not change the behavior of the pipeline.

This ensures that `C.TIME_UNSET` is more clear in dump files. Some of
these call-sites will **never** pass `C.TIME_UNSET`, but it seems
clearest to always use `addTime` and maybe it will ensure when these
sites are copied in future, `addTime` will be used in the new location
too.

Add ctts box implementation to handle muxing B-frame videos.
Add method convertPresentationTimestampsToCompositionOffset to
provide sample offsets. Return empty ctts box in case of video
does not contain B-frame. Add ctts box to MoovStructure to handle
muxing the video containing B-frames.

also makes the setter more flexible by ignoring the value of the setter when the output is hdr rather than throwing (since all HDR content must be have a linear color space)

Instead of initializing the video sink outside the renderer with an
empty format for composition preview, we initialize it in the renderer
with the input format for video.

Before this CL, if all the video (resp. audio) samples were fed before
the audio (resp. video) output format was reported, the
SequenceAssetLoader was incorrectly reporting a MediaItem change with a
null format.

Transformer's input shouldn't be constrained to the number of playable audio channels on the current device because the media may be edited (to mix channels for example) or encoded for playback on another device (a server for example).

The raw audio decoder's output audio format is stereo when the number of input
channels is (for example) 10 channels. Add a temporary workaround that uses the
input channel count for raw audio. This code should be removed in future when
we bypass the decoder entirely for raw audio.
Tested manually on a WAVE file with 18 audio channels.

Before this CL, currentInputBufferBeingOutput was set to null without
adding the buffer to the queue of available buffers, which was making
this buffer unusable. After multiple seeks, playback was stuck because
the AudioGraphInput had no input buffer left.

After this CL, Transformer will throw if the clipping start and end
positions are the same because MediaMuxer doesn't support writing a
file with no samples. This should work once we default to the in-app
muxer.

Reduces flakiness of tests that assert on PCM audio. Tests now have to
clearly choose how they want the capturing muxer to handle pcm audio.
Note that the only dump files that have changed are those that deal
with PCM audio (.wav, sowt, twos, silence). Because of the continuous
nature of PCM, timestamps are not part of the dump.

the output format conatins key information about the output of the assetloader being hdr, so we must signal the output format, not the input format to the sample exporter
fixes mh ultraHdr test failures.
Also discovered images created are very device specfic so got rid of the pixel tests, we have pixel tests in the effects library that cover the same case.

If the mixer is reset without resetting maxPositionOfRemovedSources and
then reused, the value of maxPositionOfRemovedSources can be outdated,
leading to an incorrect number of bytes being output by the mixer.
