Add Time and Grid Info

[K7MDL2]

Extract GPS NMEA data and display it
Extract if available, maidenhead grid square location (on CI-V bus?), else calculate it from NMEA data.

Lat , long, Time, Date and time offset are available on the IC-905 via CI-V with 2 commands. I now use those to set the clock on the display. Can choose UTC or LOCAL time (offset or no offset) with #define UTC in RadioConfig.h. The GPS data is passed though untouched and unmonitored.

Next up is to calculate Grid Square and display it. I have the code to do that in another project so just need to cut it in.
