Compound aprs paths

• Some APRS paths can be combined to achieve different effects.
• Low-level home digipeaters will ignore WIDE2-2 or higher to prevent congestion.
• A path such as WIDE1-1,WIDE2-2 would:
• Take advantage of a home fill-in digipeater or a high-level digipeater on the first hop
• Use wide area, smart digipeaters on subsequent hops
• Different combination of paths can reduce congestion on 144.390 MHz
