ADSB - Use extended OSD glyphs for dot in numbers and improve aircraft warni…

[error414]

It's improvement of ADSb and ADSB in OSD

• rewritten distance calculation for ADSB vehicle, used core INAV functionality
• optional second line for ADSB
• for vehicle direction to vehicle used cardinal icon, to match with formation flight
• for vehicle direction used arrow, to match with formation flight
• use internal INAV OSD formating for altitude, speed, and distance

All information what is changed is in docs/ADSB.md

Inav configurator PR: iNavFlight/inav-configurator#2391

Note:

• so far picoADSB does not fully work, picoADSB sends wrong information abou validity of position and altitude
• this pull request contains fixed cardinal icon for DJI, see screenshot. So cardinal icon for ADSB does not match with formation flight, formation flight in DJI OSD is 180 degrees off. Cardinal icon for formation flight is fixed in PR Fix cardinal OSD icon for DJI #10871
