This should help avoid destructive phase interference. The occlusion low-pass
filter is still applied in the time domain due to no clear topology (cutoff
frequency, slope, bandwidth, etc).

Resample HRTFs in the frequency domain in makemhr
...
This should produce far better results given it works directly on the frequency
response magnitudes prior to phase reconstruction, as it doesn't deal with a
linear phase filter on a truncated time-domain response (with the result also
getting truncated in both direction).
The in-library on-load HRTF resampler still uses the linear filter due to its
relative performance and simplicity benefits. It's good enough as a backup,
though users with custom HRTFs would benefit from resampling when creating the
mhr (adjusting its window size as appropriate/desired).

Use the peak IR magnitude to get the onset
...
While maybe not technically correct, we actually only care about the difference
between onsets (any base constant is removed). This should work better since it
determines when the IR is most audible, whereas previously it used a variable
threshold of when it reached 15% of the max amplitude.
An even better method may be to check where the IR amplitude exceeds a fixed
threshold (i.e. the same threshold applied to all IRs), but that would need
tweaking to find a level that doesn't catch random noise and doesn't
potentially miss the more occluded IRs.
