Waveshare 2.7B

[phaethon]

Apparently, it does not work with other display sizes. Mine is 2.7B and it detects it as 2.9, and no output on the display. Waveshare standard demo works well.

I'm guessing its because its not listed here:

https://github.com/oprema/Waveshare-E-Ink/blob/master/main.py#L9

And therefore the constructor for Epd is not set up properly

Might be worthwhile to have a look at the sample code from the standard demo and see if the device type is listed somewhere there.

For example, I am looking right now at adding support for the 2in7 HAT, and it looks like the python library for that is different!
