InkHUD Extended ASCII (#6768)

* Custom AdafruitGFX fonts with extended ASCII encodings

* AppletFont handles re-encoding of UTF-8 text

* Manual parsing of text which may contain non-ASCII chars

* Display emoji reactions, even when unprintable
Important to indicate to users that a message has been received, even if meaning is unclear.

* Superstitious shrink_to_fit
I don't think these help, but they're not hurting!

* Use Windows-1252 fonts by default

* Spelling

* Tidy up nicheGraphics.h

* Documentation

* Fix inverted logic
