This PR adds support for changing ICMP listen address. Currently, the listener listens on 0.0.0.0. This PR adds support for changing the address, for example to 127.0.0.2.

I needed to execute both client and server on the same host. Otherwise, how do you test it? When executing both on the same host, ping and pong results in an infinite loop, because client handles ping and pong at the same time, as ping traffic have same address as client. Same logic for server. Same logic for other ICMP traffic. After specifying 127.0.0.1 for client and 127.0.0.2 for server, the problem resolves.
