Much more simple method of only having data in body be joined by commas
and tacking that onto a packet type indicator to avoid having to remove a
comma later. This was suggested in comments on #27.
Per @rossengeorgiev comments on #27 I now use a dictionary with lists to
hold telemetry similar to how aprslib holds telemetry when parsed from
comments.
Modeled off of the PositionReport class, I created a TelemetryReport and
used similar serialization to create a working packet that was uploaded to
aprs.fi for testing.
