[aprssig] APRS symbols 1.3? FLOOD Gages and Radiation

You need to connect to the firenet.us feed to see the water stations.  
There's LOTS of them!  They may not be sending weather-formatted data, 
but there's a bunch of stations.

Also, the capital-W is in use by stations that aren't currently weather 
stations (see below for a short list of packets).

I'm still asking myself "why change what's working" (_ and w with 
weather) instead of just extending it to include the new features (add 
defined overlays).

If you've got a station that can detect a change in measured value to 
change its symbol to a hazard, it's probably smart enough to keep 
transmitting the existing weather data and ADD an appropriate area 
object to indicate the hazardous condition which actually makes it more 
easily noticed than a morphing station symbol.

I'm just struggling to see what the 4 weather-data-containing symbols 
gets us as opposed to extending the existing 2.
