Would appreciate support for EPD_4in2

[VictorioBerra]

Spec https://www.waveshare.com/w/upload/6/6a/4.2inch-e-paper-specification.pdf

Link to C example https://github.com/waveshare/e-Paper/blob/master/RaspberryPi_JetsonNano/c/examples/EPD_4in2_test.c

I tried to make my own configuration, but I dont really understand how to read the command table in the specs as I am a noob.
