Update the second-order decoder for HRTF
...
This uses fewer virtual speakers to help with clarity. The fewer speakers used
for the response, the less destructive phase interference there should be.

Store HRTF delays with some fractional precision
...
Since the delays get bilinearly filtered before use, maintaining a bit of extra
precision can help accuracy even if it ultimately gets rounded to the nearest
integer before use. This should help with resampled HRTFs, which need to scale
the delays that are already rounded, and can also be leveraged by an updated
MHR format.

Limit HRTF ambisonic decoding to second-order

The generated third-order matrix has incorrect first-order coefficients,
indicating a wonky decoder. The generated second-order matrix looks more
stable.

Avoid holding HRTF accumulation samples per-source
...
It notably simplifies things to mix HRTF sources into an accumulation buffer
together, which the Dry buffer's Ambisonic-to-HRTF decode is then added to,
before being mixed to the Real output.
