The volume should have been twice what it was, because I got this scale
wrong. The correct scale for Accelerate inverse FFT is 1/4 per sample,
not 1/8 like I accidentally misread while rewriting a convolver for the
umpteenth time from scratch.

7.0 downmix was passing parameters to cblas_scopy backwards, and WAV
files report "host" endian, not "native".

This should fix some coding issues, and also fix some potential memory
leaks in the file verifier, assuming it didn't already release the
files it was pulling the stats from.

The filter wasn't properly freeing its FFT setup state, and also was
unnecessarily null checking the pointers before passing them to the
aligned free function, which already does null checking.

Implement the ability to configure and select an HRIR preset to use with
the HRIR filter, or remove the preset. It will validate the file's
usefulness before setting it for the player to use.
Also, fixed back center channel filtering for 7.0 format audio.

This is needed for HeSuVi no-echo impulses, which are only one channel
per input channel, and mapping uses symmetrical mirroring of the input
set to create the surround effect, since there's no side-to-side delay
in these impulses.
This new virtualizer uses the Accelerate framework to process samples.
I've bundled a HeSuVi impulse for now, and will add an option to select
an impulse in the future. It will validate the selection before sending
it to the actual filter, which outright fails if it receives invalid
input. Impulses will be supported in any arbitrary format that Cog
supports, but let's not go too hog wild, it requires HeSuVi 14 channel
presets.
