E-Ink Screensaver (#3477)

Browse Source 
* fix Wireless Paper double-clear screen at boot

* log when flooded with "responsive" frames

* show the "resuming" screen when waking from deep-sleep

* rename drawDeepSleepScreen
avoid future confusion with "Screen Paused" screen

* show a screensaver frame when screen off
The frame shown during deep sleep is now also passed through showScreensaverFrames()

* Add macros for E-Ink color values.
OLEDDISPLAY_COLOR is inverted. Result of light-mode on E-Ink vs dark-mode on OLED?

* adapt drawDeepSleepScreen to new screensaver convention

* Mark Wireless Paper V1.1 as having problems with ghosting
Any other issues can be marked in a similar way, then handled in code where relevant

* Change screensaver from fullscreen logo to overlay

* identify "quirks" rather than "problems"

* move async refresh polling from display() to a NotifiedWorkerThread

* Prevent skipping of deep-sleep screen
(Hopefully)

* Redesign screensaver overlay
Now displays short name

* Optimize refresh for different displays

* Support older EInkDisplay class

* Don't assume text alignment

* fix spelling of a quirk macro
(No impact to code, but avoids future issues)

* Handle impossibly unlikely millis() overflow error
Should have just let it go, but here we are..
