This patch includes a completely reworked client structure.
There is now only 1 client object, that loads the appropriate
drivers. The drivers are fake, aprsis and tcpkiss.
The TCPKISS client was written from scratch to avoid using asyncio.
Asyncion is nothing but a pain in the ass.
this patch refactors the client, drivers and client factory
to use the same Protocol mechanism used by the stats collector
to construct the proper client to be used according to
the configuration
this patch removes the need for dacite2 package for creating
packet objects from the aprslib decoded packet dictionary.
moved the factory method from the base Packet object
to the core module.
