Jeff Epler d5a2293784 nrf52840: allow 12 voices
In my testing, the feather bluefruit can do 12 voices at 48kHz!
This is a simple case (no LFOs, no ring modulation) so other situations might
require a lower sample rate, fewer voices, or both.

The sound is a little artifacty & low-fi but I think that's down to the speaker
& use of PWM instead of I2S.
