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.

Unlock the audio decoder mutex before disabling events in alffplay

The callback may be waiting on the mutex, but disabling the callback needs any
current invocation to finish first.

Make sure the reverb fading completes
...
The processing loop doesn't depend on being aligned anymore, so it won't get
stuck when only less than 4 samples can be done in a non-final update.

Rework reverb A/B-Format conversion mixing

This should help improve performance using the optimized mixers, and fewer
passes on the transforms, though at the cost of more memory.

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.

Remove RESTRICT from the bandsplitter process method
...
The compiler can see there's no aliasing with the local variables, and the
input/output buffers are handled sequentially one element at a time anyway.

Allow processing some effects in higher order ambisonics
...
Reverb notably is still only first-order (any higher order channels are
dropped, and it writes to FOAOut). But others, like the equalizer, work on all
available channels.

This preserves the original phase of the HRIR frequencies for decoding the
