Connecting the same SH110X display using same library same example

Example: https://github.com/adafruit/Adafruit_CircuitPython_DisplayIO_SH1107/blob/main/examples/displayio_sh1107_simpletest.py

From: https://learn.adafruit.com/adafruit-128x64-oled-featherwing/circuitpython

ESP32 CircuitPython works as expected same screen output produced https://learn.adafruit.com/assets/95402

BLINKA MCP2221 same example produces garbled display

FeatherWings are meant to be used with Feather main boards.
