This experiment with Constant Q Transform was interesting, and it's nice
to see that it actually functions, but it's just too damn slow to really
be useful for visualization purposes. It uses nearly a full core on an
M1 processor, and I'd hate to see what it does on an Intel machine.
Stashing this in a branch and discarding it from the main tree, in case
somebody finds this code useful some day.

IN A.D. 2101, WAR WAS BEGINNING. *boom*
Yeah, this was a dumb bug, I didn't realize that AUAudioUnit would just
arbitrarily ignore my configured block size and request a different one.
The AirPods Pro will just request 480 instead of the 512 I ask for, so
let's instead support variable block sizes, and only take up to the last
4096 samples of the chunk fed to the output device.

Borrowing some DFT code from deadbeef, this implements a simple spectrum
visualization into the main toolbar of the app.
