Replace 4 separate all-passes with one vector all-pass
...
Each 4 related all-passes now share a structure with one delay line, which uses
an interleaved sample history. Also fixes some potential rounding problems for
delay lines with interleaved samples.

Apply reverb modulation to the late feedback lines
...
This seems to be more in-line with the intended behavior, to allow build-up and
overlap within the reverb decay, rather than a pitch-shift on input.
Unfortunately there's no readily available implementation of this reverb model
that includes modulation to compare with, so a low depth coefficient is used to
keep it very subtle.

Remove the 0.5 gain on the reverb output

Turns out to be unnecessary, as it reduced the volume below what other reverb

Reduce LIMITER_VALUE_MAX
...
The previous value couldn't actually be expressed as a float and got rounded up
to the next whole number value, leaving the potential for an overrun in the
squared sum.

This helps keep the squared sum stable over larger updates, also avoiding the
need to keep recalculating it.

Update AL_SOURCE_SPATIALIZE_SOFT value
...
Though it didn't strictly clash since it was for a different component (global
state vs source property), 0x1213 was used by AL_RESAMPLER_NAME_SOFT. Probably
best to avoid duplicate property values regardless.

Rename Zero-Order Hold to Nearest
...
A bit of a misnomer now since "Nearest" implies rounding (i.e. when the sample
offset is >= .5, it should pick the next sample being closer in time), but that
adds unnecessary complications.

This is a bit more efficient than calling the normal HRTF mixing function

Reimplement bilinear interpolation between HRIRs

Some data sets are just too sparse, having noticeably few measurements to
properly handle slowly panning sources. Although not perfect, bilinearly
interpolating the HRIR measurements improves the positional accuracy.

Fade HRTF coefficients over 64 samples at most
...
This greatly improves HRTF performance since the dual-mix only applies to the
64-sample coefficient transition. So rather than doubling the full mix, it only
doubles 64 samples out of the full mix.
