Hello message

NOTE: 16 bits (2 bytes) may be prepended to the serialized message indicating the total length
      in bytes of the message, resulting in the maximum length of a message being 65_535 bytes.
      This is necessary in those stream-oriented transports (e.g., TCP) that do not preserve
      the boundary of the serialized messages. The length is encoded as little-endian.
      In any case, the length of a message must not exceed 65_535 bytes.

The HELLO message is sent in any of the following three cases:
    1) in response to a SCOUT message;
    2) to (periodically) advertise (e.g., on multicast) the Peer and the locators it is reachable at;
    3) in a already established session to update the corresponding peer on the new capabilities
       (i.e., whatmai) and/or new set of locators (i.e., added or deleted).
Locators are expressed as:
<code>
 udp/192.168.0.2:1234
 tcp/192.168.0.2:1234
 udp/239.255.255.123:5555
<code>
