ifdef around optional fonts to reduce flash size/time. (#339)

Browse Source 
## Summary

Adds define to omit optional fonts from the build. This reduces time to
flash from >31s to <13s. Useful for development that doesn't require
fonts. Addresses #193

Invoke it like this during development:
`PLATFORMIO_BUILD_FLAGS="-D OMIT_FONTS" pio run --target upload && pio
device monitor`

Changing the define causes `pio` to do a full rebuild (but it will be
quick if you keep the define).
