Avoid infs/nans in the crest detector
...
It needs to be investigated why the rendered mix sometimes has such large
sample values when starting, but the compressor/limiter shouldn't generate NaNs
because of it.

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.

Readjusted the bsinc12 cutoff back to -60dB. Also increased the filter's phase
count.

Add "fast" variants for the bsinc resamplers
...
This simply omits the scale factor from the filter, similar to how up-sampling
does. The consequence of this is less smooth transitions when ramping the
pitch while down-sampling, but otherwise behaves fine.

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.

Avoid storing an integer in a pointer
...
C++ does not guarantee that, given an int of sufficient size, converting
int->ptr->int will result in the original value. A pointer may have more than
one integer representation. Only ptr->int->ptr round trips are well-defined.
