Implement a state machine #113

We're in the situation now where the NATS client connection can be in many states e.g. preconnection, fatal error, invalid message in buffer etc. Using a state machine could reduce the complexity of handle states going forward.

States:

Initialised
Connected
ConnectionError
EmptyBuffer
NonEmptyBuffer
FullBuffer
InvalidBuffer
OverloadedMessage
InvalidMessage

Possible we need a top level state machine and a buffer state machine 🤔
