[aprssig] APRS-IS Object Filter Syntax

What object(s) are  you trying to get passed to you?

The o/ filter requires the full object name, or a wildcard if your 
object name isn't a full 9 characters.

And there's no way to filter on an object name AND a distance with the 
standard filters.  The non-negated terms are OR'd together (matching any 
single term passes the packet) while the negated terms are AND'd after 
that (matching a single negated term does NOT pass the packet).

PS.  I'm implementing a + modifier in my internal filter implementation 
in APRSISCE/32 that can do what you're after but it's not part of the 
standard filter.
