1d91e282c8 Update the MHR format 
This update removes the 16/24-bit sample type enum, now always being 24-bit
(other than a very small size saving, there's no practical benefit to storing
16-bit samples). This also reverses the field storage, so no on-load fixup is
needed, and stores the IR delays with 2 bits of sub-sample precision, allowing
for slightly better timing (after resampling, blending, etc).

c182a3376a Blend the whole IR for the interpolated HRIR 
The SIMD mixers may use a few more elements beyond the irSize, so not limiting
the blend to that size can slightly improve the quality for resampled HRIRs.

1a2438b09c Don't blend the B-Format decoder HRIRs 
Though fine in theory, an issue arises with extra phase interference since the
frequency phases aren't aligned for each response. It would be better to do the
blending before minimum phase reconstruction, where it can blend just the
frequency magnitudes, essentially allowing makemhr to increase the resolution
of the dataset.

053de62398 Don't force the HRIR length to a rounded value 
The coefficient and accumulation buffers are guaranteed large enough for the
full size, and the SIMD handlers will behave the same either way.

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.
