Feature request - N/S W/E radio buttons next to Latitude/Longitude

[KM6IAU]

Every now and then a node with an American call sign pops up in China on the meshmap, because someone forgot to put the minus sign in front of the Longitude.

Putting in N/S W/E radio buttons might make this possible oversight more apparent to the user.

Something like this, in pseudocode:

if (lat < 0) {
    /* we can reasonable assume they meant S, 
       regardless of the radio button */
} else {
    /* it is possible the negative sign was forgotten */
}

if (lon < 0) {
    /* we can reasonable assume they meant W, 
       regardless of the radio button */
} else {
    /* it is possible the negative sign was forgotten */
}

if (radio_lat == "S") { 
    lat = abs(lat) * -1;
} else { 
    /* they either appropriately selected "N" or 
       appropriately entered a S lat with negative 
       number */
}

if (radio_lon == "W") { 
    lon = abs(lon) * -1;
} else { 
    /* they either appropriately selected "E" or 
       appropriately entered a W lon with negative 
       number */
}

Or more simply:

if (radio_lat == "S") { lat = abs(lat) * -1; }
if (radio_lon == "W") { lon = abs(lon) * -1; }
