Asyncio based port to CircuitPython

[bablokb]

Not an issue, but a pingback.

Your nice project inspired me to port it to CircuitPython (which is almost trivial), but I ended up with a complete new implementation based on asyncio (see https://github.com/bablokb/cp-buzzer-music). Mainly because of one of the issues here (MemoryError with long songs: #6). The new implementation can read from a file and pipes the notes to the buzzers, so the memory footprint is minimal regardless of the length of the music.

Backporting this to MicroPython is certainly not very complicated, since low-level access to PWM is the main difference.

Amazing! Great job, and thank you so much 😄! I'll look into this when I have some time.
