Add some quantization support to the random pitch feature.
Use knob1 to set the pitch distance/

The attached bin file can be flashed to the pod via DFU using:
dfu-util -a 0 -s 0x08000000:leave -D grnltr_pod.v0.99g.bin -d ,0483:df11
To program and elf file via openocd and a stlink:
openocd -s /usr/local/share/openocd/scripts -f interface/stlink.cfg -f target/stm32h7x.cfg \
-c "program ./build/grnltr_pod.v0.99.elf verify reset exit"
Replace grnltr_pod.v0.99g.bin with grnltr_bluemchen.v0.99g.bin above for the bluemchen.
