WatchFaceDigital.cpp: make it configurable (by code only) #958
Description
I really like the WatchFaceDigital, but I would like to make it configurable (i.e., make it less distracting):
- I would like to make all icons gray
- I would like time + date only variant (no icons)
Within in the watch face settings: I would just show them as different variants.
Should not require duplicating that much code.
