b8d73a226a Add a 2D fourth-order upsampler 
This will be necessary for 2D fourth-order sources with 3D fourth-order output.

35d7fca52c Don't mark a non-constexpr-able function as constexpr 
It can't be constexpr because it needs write access to an std::array, and
because of std::sqrt.

1ee81ab3f0 Fix W input mixing when non-0 coverage 
When upsampling certain ambisonic formats, the W channel may contribute to
other output channels even with full coverage. Make sure they're taken into
account.

298318bd8a Apply the upsampler before rotation 
Although this will necessitate applying a full device-order rotation for all
ambisonic sources, it should be slightly better since it's effectively rotated
after being mixed to higher order. This will also allow using more optimized
upsamplers for 2D ambisonic sources vs 3D (while still allowing the sources to
be rotated in 3D).

df33746571 Create a proper third-order upsampler matrix 
This is just an identity matrix for now, since with third-order mixing, it
results in a matrix being multiplied with it's inverse.

19d35a45d7 Use an intermediate buffer for writing to the ringbuffer 
It doesn't seem as though AudioUnitRender likes being given two buffers to
render/capture samples into segmented memory.

6d5580805e Use a decode-encode method for ambisonic upsampling 
This should allow for clearer and less diffuse responses. While a cube is in
the blindspots for second-order, resulting in an identify transform for first-
to-second-order, they do start contributing to third-order channels, which
should make for sharper virtual points. The fixed HF scales should also play
nicer with larger order upmixes.

b286e6497f Rework multi-channel source radius handling 
Rather than applying the calculated spread to each virtual channel, the spread
indicates how much the virtual channels surround the listener. At full spread,
the channels retain their virtual speaker positions, while at no spread, all
channels converge on the source position. This behavior is more consistent with
B-Format sources.
