The client registry defined a protocol that all drivers had
to implement. This patch ensures that all methods are
consistent in the protocol definition.
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.
