This is my implementation, I'll try to get around to a PR when I can. Note the original code may have changed since I made this, but you should be able to try and get the diff of this vs the real one to see what I changed. class EPD_2in13_Landscape(framebuf.FrameBuffer):

In Pico_ePaper-2.9.py there's a class for Portrait and a class for Landscape display.
Using this, I have adapted Pico_ePaper-2.13.py example to work in landscape. I'm happy to submit this change as a PR if you're interested - let me know!
