[aprssig] TT4 Config for High Altitude Balloon

There's a bug apparently in the Tracker2 (IIRC) digipeater code that 
will do as you describe with a WIDE2, but in fact, if you think of the 
WIDEN-n as the "n" meaning how many hops are "left", then a -0 (implied 
by WIDE2) should in fact have been marked used by whatever created it.  
WIDE2-1 requests a single hop from a WIDE2 digipeater by what I've seen 
described. If WIDE2 works, then I'd personally call it a bug, not a feature.
