waveshare_epd.epd1in54_V2 wrong init()

[robweber]

          I tried omni-epd with a waveshare_epd.epd1in54_V2.

omni-epd-test fails with

Loaded waveshare_epd.epd1in54_V2 with width 200 and height 200

Looks like this parameter is requested by the waveshare drivers:

venv_epd/lib64/python3.11/site-packages/waveshare_epd/epd1in54_V2.py:    def init(self, isPartial):
venv_epd/lib64/python3.11/site-packages/waveshare_epd/epd1in54_V2.py:        if(isPartial):

Confirmed at source that epd1in54_V2 needs the alt init parameter.

@W11T - please test if you have time
