Release 8.2.1: aprslib is a declared dependency (#20)

Picks up the fix from #19. The deb now declares python3-aprslib, and the
try/except ImportError shim around the aprslib import is gone.

That shim was the actual defect. aprslib is not optional -- every frame
goes through aprslib.parsing.parse -- so catching the ImportError did not
degrade gracefully, it just moved the failure somewhere unreadable and
turned a clear "No module named 'aprslib'" into a confusing runtime
error much later. The deb never declared the dependency either, so an
apt install produced a package that could not parse a single frame.
