Jonathan de Jong b1248ff315 enforced f-strings everywhere, %s on logging
extended _multiaddr_from_socket to support UDP and IPv6 automatically
changed TCPListener to use _ip4_or_6_from_multiaddr to get host, and not ip4 only

enforced `from error` everywhere with raises
added call braces to exceptions
