* Improve handling and logging of unsupported owntracks message types
Added generic handlers for message types that are valid but not
supported by the HA component (lwt, beacon, etc.) and for
message types which are invalid. Valid but not supported
messages will now be logged as DEBUG. Invalid messages will
be logged as WARNING.
Supporting single "waypoint" messages in addition to the
roll-up "waypoints" messages.
Added tests around these features.
