Init argument names should not use Pin

[FoamyGuy]

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.

Is this correct? I don't see reference to *_pin arguments, or do they come from displayio.EPaperDisplay?

@FoamyGuy I think this should be closed since it doesn't seem to be an issue with this library. There aren't any pin/IO arguments to the main class in this library, and even the base EPaperDisplay seems to only have one _pin argument which does take a Pin object according to the docs.

Yep, I don't see any DigitalInOut's either, closing this
