a8d06c0731 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.

74cbba511d 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.

c5f88ab59f EFX: Add explicit cast to a square function 
MSVC 2015 and above returns the expression according to its datatype.
In this case, returns 4294967295 instead of -1.

d2608e4bde 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.
