Don't use custom decoder configurations with mono or stereo
...
By default, stereo outputs using UHJ, which renders to a B-Format buffer that
gets run through a UHJ encoder for output. It may also output using pair-wise
panning, which pans between -30 and +30 degrees with the speakers at the two
ends. In both cases, the stereo coefficients are ignored.
Mono, having only one output channel, can realistically only attenuate its
channel. Turning the volume up and down accomplishes the same result.

Add distance compensation to the HQ decoder
...
This only compensates for timing and gain differences caused by differences in
the physical speaker distances. It's not near-field compensation. This also
relies on having proper distance values defined in the ambdec definition file.

Allow second-order HQ decoding
...
Could really do with some optimizations to the mixing gain calculations. For
ambisonic targets, the coefficients will only have 1 non-0 entry for each
output, so the double loop in unnecessarily wasteful. Similarly, most uses
won't need a full height encoding either, so a horizontal-only or mixed-order
target could reduce the number of channels.

Add a dual-band ambisonic decoder
...
This uses a virtual B-Format buffer for mixing, and then uses a dual-band
decoder for improved positional quality. This currently only works with first-
order output since first-order input (from the AL_EXT_BFROMAT extension) would
not sound correct when fed through a second- or third-order decoder.
This also does not currently implement near-field compensation since near-field
rendering effects are not implemented.

There seems to be some inconsistent info about whether W should be scaled by
