This all started with a bug where the clock wouldn't update appropriately, and ended with a whole refactoring to support later playback in the timeline. Playback and recording instances are now independent, and this applies to the <Playback* /> components as well. Instead of those playback components taking a recording, they take a playback instance which has all the information the components need. The clock was incredibly difficult to do because of the audio context's time tracking and the source's inability to say where it is at in the buffer/in time. This means we have to track when we started playing the clip so we can capture the audio context's current time, which may be a few seconds by the first time the user hits play. We also track stops so we know when to reset that flag. Waveform calculations have also been moved into the base component, deduplicating the math a bit.
