ESP32-S2 PWMOut Error

[makermelissa]

Reported by @jedgarpark. The error comes up after a while of pressing the buttons, but he's not able to figure out if it is some specific pattern. It works fine about 95% of the time. It looks like simpleio attempts to use audiocore if there's a ValueError thrown from pulseio.PWMOut().

Here's the error:

Traceback (most recent call last):
  File "code.py", line 81, in <module>
  File "adafruit_magtag/peripherals.py", line 71, in play_tone
  File "simpleio.py", line 80, in tone
NameError: name 'audiocore' is not defined

Here's the code that triggered it:

This could be caused by filesystem corruption.
