Don't look up the dry buffer's FrontCenter in the Dedicated effect
...
The real FrontCenter output is used if it exists, and if it doesn't, it's
unlikely the dry buffer will have it (and even if it does, it won't be any
better than panning).

More directly map coefficients for ambisonic mixing buffers
...
Instead of looping over all the coefficients for each channel with multiplies,
when we know only one will have a non-0 factor for ambisonic mixing buffers,
just index the one with a non-0 factor.

Use the 3D panned output for reverb with HQ decoding
...
This is less than ideal, but matching each reverb line to a speaker with
surround sound output is way too loud without the ambient volume scaling
offered by the "direct" panning.

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.
