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

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.

Partially handle ambisonics in alffplay
...
This is currently really only applicable to Opus-encoded files. It assumes
AmbiX (SN3D normalization, ACN ordering) and only comes into play when the
channel layout is blank. FFmpeg/libavcodec doesn't have a way to detect
B-Format input or what normalization and ordering it uses. Note in particular
.amb files do not play correctly (libavcodec seems to apply a default channel
layout for 4-channel wav-type files, regardless of its channel mask value).
