Queue now has a separate 'ready' property to indicate it's ready to be used, which is independent from whether it's still loading tracks in. This also improves the response time for shuffling all tracks (we will initially pick a random track in the first 100 tracks whilst the rest of the tracks are loading). This should also fix issues where one song will start playing and then repeat itself when the queue finishes loading, and hopefully solve #160 as well (though I couldn't actually repro this myself).

I think this is what most folks would expect to happen if BT is
disconnected/disabled and the headphones are removed.
Also, I think(?) this fixes one situation where the device doesn't idle/
sleep when folks would expect it to (not connected to headphones or bt).
It's currently quite limited (no stereo or sample rate conversion,
multiple messages clobber each other, only plays if music is playing),
but we're getting there!
This allows the audio pipeline to remain responsive even when the drain
buffer has completely filled. This in turn means that you now see the
track info in the 'now playing' screen change if the current track
changes whilst you are paused.
Since I was fucking around a lot in the audio processor anyway, I also
added mono->stereo expansion so that playing mono tracks on Bluetooth no
longer destroys your ears.
the i2s handler and streambuffer metadata are both still in iram for
good performance. otherwise, this seems to be enough to make gapless
playback work.
