ESPHome configuration for the Pocuter One

The Pocuter company appears to have imploded leaving the devices less useful.

I have a few of them that I wanted to make use of, and I couldn't find an existing ESPHome configuration, so I made one. Sharing it here in the hopes it helps someone else revive their hardware.

PRs welcome.

# Accelerometer
# Theoretically the MXC4005XC can measure both acceleration and temperature
# I suspect the temperature reading will be wildly inaccurate and not useful
# No ESPHome integration directly exists for this component anyway and give the above it's not sufficiently useful for me to write my own
# Anyone reading this who feels ambitious, try this https://github.com/honnet/MXC4005XC
# It's just an I2C device so it shouldn't be too bad

# Microphone
# There is a microphone connected to pin 0 on the main chip, intended for use as incoming PWM for consumption by the ADC
# As far as I can tell one is intended to capture the raw waveform somehow and save that:
# https://github.com/pocuter/PocuterLib/blob/master/include/hal/esp32-c3/pwmSound/pwm_audio.h
# I couldn't immediately figure out the best way to do this in esphome, and also I don't currently have need of a microphone, so
# I'm leaving this out for now.
