Dave Cheney 3b4cdece03 examples: add 2.13in e-Paper V1 demo for RP2040-PiZero ...

Exercise all four SetRotation modes in the demo. Fix epd2in13.Size(),
which reported the padded logical buffer width instead of the true
panel width at rotation 90 and 270. This clipped the last few rows on
those rotations because the driver bounds check used the true width
while Size() reported the padded width.

Scale the dither ramp and solid block to the panel height instead of
fixed pixel offsets, so they fit inside the shorter 122 pixel dimension
at rotation 90 and 270.
