We recently changed argument names for initializing the ESP32SPI library to use the suffix _dio rather than _pin because the arguments need to be instantiated DigitalInOut objects, not microcontroller.Pin objects.

See: adafruit/Adafruit_CircuitPython_ESP32SPI#121

This library uses the same *_pin names for it's arguments which are also expected to the DigitalInOuts rather than Pins.

I think we'll want to change the names here and any other libraries that have _pin to keep things consistent across libraries.
