Add a queue system to RTU master
The serial bus protocol specifies that each request is followed
by a response (unless a request does not require a response e.g.
broadcast requests). Therefore if the user sends of multiple requests
the master has to enqueue them for later sending.
Timeout handling, retry after timeout and send limitations on bus will
be added later on.
