Support for surround sound virtualization via convolution #50

Surround sound is extremely rare on non-TV Android OSs (not including spatial audio like Dolby Atmos/Sony 360 Reality Audio), probably because most devices just don't support anything beyond 2 channels.
So I wonder if JDSP could expand the convolver support to virtualize 5.1/7.1 surround sound using HRTFs (convolver IRs for front, side and rear speakers) so that we can hear surround channels as if they were speakers in the same room, like HeSuVi can do on Windows.

I should probably mention that I managed to convert HeSuVi HRIRs to a convolver file compatible with Viper4Android (and JamesDSP)

Just needed to delete all but the first 2 HRIR channels, then duplicate the 2nd into the 3rd, and the 1st into the 4th, save as 32bit float WAV into the Kernel folder. However, this will just result in virtualized stereo. What I'm looking for is to do this, but also for the side and rear channels.
