add glyphs for 32x128 and possibly add contrast option

[Proto-molecule]

I made a few glyph additions for the 32x128 size.

• added 2x1 glyphs and maybe they'll look better, or maybe they make things look more cluttered... idk.
• also I added 3x3 glyphs for the overlay.

Also I added a new screen to address the "lack of contrast" problem I've been seeing with the 64x128 displays I've been getting on amazon. the issue is discussed here it may be just me so the code addition may not be worth it. I thought I would at least throw it in so you could take a look for yourself. "Vcom deselect" seems to be the culprit. maybe there just a function to adjust the setting rather than loading a whole new screen class.(ill continue digging around myself)

Have pulled this into different branch and I can see small improvement in legibility but the code size increase is not insignificant. I think it would make sense to reduce 6x6 and 3x3 fonts to just the necessary glyphs and omit others to save some precious flash. As far as the low contrast fix goes it may be better (or simpler) to add another type instead of another config option? What happens if yo use it on regular display?
