 Dead letters are automatically emitted when a message cannot be delivered to actors' mailbox or when an Ask times out.
 Also, one can emit dead letters from the receiving actor by using the `ctx.Unhandled()` method. This is useful instead of panicking when
 the receiving actor does not know how to handle a particular message. Dead letters are not propagated over the network, there are tied to the local actor system.
