200c164d78 Improve HRTF delay handling 
Ensures source-level HRTF, the dry mix, and direct output all align properly,
and simplifies adding the delay in the direct mix output.

825206bfa2 Apply the ambisonic HF scaling in real-time with HRTF 
Rather than applying the HF scale to the IRs necessitating them to be truncated
along with increasing the IR size, it can be applied to the input signal for
the same results. Consequently, the IR size can be notably shortened while
avoiding the extra truncation. In its place, the delayed reversed all-pass
technique can still be used on the input for maintaining phase when applying
the bandsplit/hfscalar filter to the input signal.

36aebbb6ae Include the existing direct signal in the UHJ delay 
So any direct_channels sources and normal panned sources remain aligned, and
the reported latency is accurate.

48fbad9836 Slightly improve the Hann windows 
There's no need to include the 0 terms on the ends since they'll never
contribute a sample. So extend the width to have the 0 terms just outside the
window where it wouldn't contribute anyway.

6823fa2de2 Improve the leftover and realignment mixing loops 
Using a mask helps the compiler recognize that the leftover (any remaining non-
multiple-of-4) and realignment loops will only have 3 iterations at most, which
it can unroll or otherwise make more meaningful optimizations for. Previously
it would try to vectorize and partially unroll the loops, which is wasteful
when there would never be enough to vectorize.
