Review: Add Communicator

[BenediktBurger]

The Communicator is a simple utility to send messages via LECO and read the answer.

It does not run in another thread and does not interpret messages (not even ping requests), unless the read method is called.

The use case is for simple scripts, where you want to send a message and read the answer without the hassle to set up other threads etc.

In order to work, the ask method has to do some checks:

• If the Coordinator tells, that the Communicator is not signed in, it signs in and sends the message a second time
• All ping requests (from the Coordinator) since the last communication are dropped, as they are meaningless, since a new message has been sent.

For easier usage, the Communicator is a context manager (at enter it signs in, at exit it signs out).

As a review is not happening in foreseeable future, I make this PRs a draft.

Whenever someone has time to review, I'll push the most recent version.
