The bit-depth/rate crusher asked its hold for 32 kHz regardless of the output rate. On MicroPython the hold node refuses a rate above the output rate, so rhythm909 failed to create at 24000, 22050 and 16000 Hz. The hold rate is now capped at the output rate (at 24 kHz the hold passes every frame, which is what the numpy path already did). Output at 32 kHz and above is unchanged: a 48 kHz render is byte-identical before and after.

Adds a MicroPython test that builds at 22050 and 24000 and plays every pad.

Closes #35
