[aprssig] Is the APRS Spec for APRS Data Type Identifier just randomly ignored? Should it be?

Also keep in mind that MIC-E packets also do not use AP* destinations, but 
are not ALTNET packets. In fact.. you cannot use MIC-E on ALTNETs since 
there is no way to indicate the ALTNET...

So before looking at the destination address to detect an ALTNET, first 
look if it is not a MIC-E packet.
