Repack the bsinc resamplers coefficients
...
This puts the base coefficients and the phase deltas next to each other. This
improves caching, as the base and phase deltas are always used together while
the scales are only used for the non-fast versions.

Implement a "fast" bsinc path
...
This takes advantage of the fact than when increment <= 1 (when not down-
sampling), the scale factor is always 0. As a result, the scale and scale-phase
deltas never contribute to the filtered output. Removing those multiply+add
operations cuts half of the work done by the inner loop.
Sounds that do need to down-sample (when played with a high pitch, or is 48khz
on 44.1khz output, for example), still go through the normal bsinc process.

Only use one accumulation buffer for B-Format HRTF mixing
...
It's all getting added together anyway and all channels are continuous inputs,
so this is fewer passes over various buffers.
