Fade out voices that end normally
...
Sometimes a sound may end with non-0 amplitude, particularly if a buffer queue
underruns. This helps avoid clicks and pops for sources that don't already end
in silence.

Add a Stopping state for voices
...
This currently doesn't do much, except have the mixer progress it to Stopped.
It's valid to have without a source or buffers, and in the future will allow
fading out when a source is paused or stopped.

Reverse the HRTF field array

Most often a sound's distance will be beyond the farthest field measurement, so
It's more efficient to have the farthest field first and avoid looping through
the whole field array for them.

Apply ambisonic upsampling on reverb output as needed
...
This isn't the greatest thing since it splits the A-to-B-Format transform from
the panning transform. The A-to-B and HF scale mixes are also not as optimal as
they could be, since they can't use the main mixer functions (wrong buffer line
length).
It does, however, get rid of the final use of the FOAOut buffer, so the
upsampling post-process is no longer needed.
