LibMedia: Give demuxer seeks an option to always seek to a keyframe
...
By default, MatroskaDemuxer chooses not to seek if the current frame
is closer to the seek target than the keyframe that precedes the seek
target. However, it can be desirable to seek to a keyframe anyway, so
let's allow that.

LibMedia: Play audio through PlaybackManager using Providers/Sinks
...
This commit implements the functionality to play back audio through
PlaybackManager.
To decode the audio data, AudioDataProviders are created for each track
in the provided media data. These providers will fill their audio block
queue, then sit idle until their corresponding tracks are enabled.
In order to output the audio, one AudioMixingSink is created which
manages a PlaybackStream which requests audio blocks from multiple
AudioDataProviders and mixes them into one buffer with sample-perfect
precision.

LibMedia: Set the time base in FFmpegVideoDecoder

Very minor change, which doesn't actually affect our output, since we

to give FFmpeg's decoder this information as well.

Most users will only care about the total file duration, and shouldn't
be required to determine the file duration from multiple track
