Add support for Automated Surface/Weather Observing Systems (ASOS/AWOS)#390

Similar to ATIS, but most common in the US at smaller airports/airfields.

In the sim, the default ATC typically has these as defined in the menu such as “Tune {Identifier} Automated Weather weather on {xxx.xx}” - where {Identitfier is the ICAO code of the airport} and {xxx.xx} is the frequency.

Many of the ASOS/AWOS systems deployed in the US have their own unique “voice” - different than the TTS frequently used at many airports for ATIS.
Here is an example from a video I found on YouTube of a commonly used ASOS/AWOS voice:

In australia we call it AWIS. Need to implement this so we can get the QNH and winds etc when departing non-towered airports

definetly would be a plus
