Description of change

Adds the hex version of the address when listing the addresses. This allows the user to identify the address in the details of transactions, outputs, etc.
Another possible solution would be using the Bech32 format when printing the Transaction, Output etc. This is not feasible, because bech32 requires HRP which is not available during formatting.
