ukewea bab0ba9c0f Change buffer sending process for waveshare_epaper (2.70in) (#1031) 
* Change buffer sending process for waveshare_epaper (2.70in)

The current way ESPhome sending buffer to WaveshareEPaper2P7In does not show the expected content on the display, this commit is changing the data transferring process so the content is showing as expected.

The process is adapted from the demo code provided by Waveshare, manufacturer of the E-paper display.

* Fix linting eror
