Feature request: Ability to specify APRS Symbol used via the config file

[mytechguyri]

Propose adding an optional config field in the [APRS] section of the config file where the end user can specify the APRS symbol to use. Make the Symbol field an option in each of the various gateway config files, as someone running multi-mode may want one symbol for their DStar gateway, and a different symbol for their DMR Gateway.

i.e. in the DMRGateway config file:

[APRS] Enable=1 Address=127.0.0.1 Port=8673 Suffix=R Description= Symbol=/r

or perhaps I have a hotspot in my RV when I'm on holiday, and I want it to show on the maps as such.

[APRS] Enable=1 Address=127.0.0.1 Port=8673 Suffix=R Description= Symbol=/R

or perhaps I'm running a portable repeater at an ARRL field day:

Symbol=Aa

The symbol tables were designed to give us all these options, so it doesn't make sense for it to be hard coded.

I actually support this, and have been working on this exact enhancement. I will submit a PR for DMRGateway shortly, and if accepted, I will do the same for the other G4KLX gateways (and MMDVM_CM programs) that have the APRSWriter built-in.

My PR #122 can close this, Jonathan.
