[BUG] screen_refresh with waveshare_2 break display

[darknao]

Describe the bug
The screen start showing garbage, or even completely crash, when using the screen_refresh plugin on the waveshare v2

To Reproduce
Steps to reproduce the behavior:

1. enable the screen_refresh plugin
2. wait for a full refresh

Expected behavior
The screen should do a full refresh, and continue to work afterward.

Environment (please complete the following information):

• 1.2.1
• pi0w
• waveshare v2

Additional context
Waveshare v2 use partial refresh all the time.
According to Waveshare specs, you should do a full refresh once in a while when using partial mode to avoid ghosting and burn in issue.
Additionally, in my case, I sometimes get quite severe ghosting + black dots in the background, and using the screen_refresh plugin seems to help.
PR about this will follow.

that is why the plugin has been moved in a separate repo that says use them at your own risk.

(also there's no real need of full screen refreshes on v2)

not according to specs : https://www.waveshare.com/wiki/2.13inch_e-Paper_HAT

Note that you cannot use Partial refresh all the time, you should full refresh e-paper regularly, otherwise, ghost problem will get worse even damage.

not according to months of testing and our customized codebase, which is different than their examples and sdk
