Adds 1.54" e-ink display (gdew0154m09) support to waveshare_epaper component (#4939)
* Added GDEW0154M09 in waveshare_epaper component * noop change - trigger workflow * Make linter happy * Update test4.yaml * linter doing linty things * revert the newline removal. * revert to prove unstable test * add code back into test. * no partial updates supported yet - removed from test. * Update esphome/components/waveshare_epaper/waveshare_epaper.cpp Co-authored-by: Keith Burzinski <kbx81x@gmail.com> --------- Co-authored-by: Keith Burzinski <kbx81x@gmail.com>
