playback: rework audio focus

Rework audio focus to rely on the native ExoPlayer implementation instead of a custom implementation. Previously, we avoided ExoPlayer's AudioFocus system as it never played after a transient lost. A few versions later now through, now it does, so we may as well switch to it. This does introduce a bug where ReplayGain functionality will conflict with audio focus, but I hope to eliminate this with #115 as I switch to an AudioProcessor instead of a callback.
