Adds [AUDIO]-prefixed logs to both single-stream and multi-stream players:
1 Hz heartbeat with rate/timeControl/mute/volume/bitrate/route, plus
immediate events on rate, isMuted, volume, currentItem, media selection,
access-log, error-log, and system audio route/interruption changes.
Grep Xcode console for `[AUDIO]` or `[AUDIO SYSTEM]` to isolate.
Also reverts the AAC-preference in pinAudioSelection: the
ballgame.treytartt.com master playlist is already all mp4a.40.2 stereo,
so the Dolby-DRC theory doesn't fit. Pin simply selects the default
audible option now.
