Add an Ord instance for ImplicitAddressWithAlias
Clarification and motivation
ImplicitAddressWithAlias
doesn't have an Ord
instance and one was needed in one case.
There's not a strong argument to add this here (see link above), but it doesn't hurt either to have one.
Acceptance criteria
ImplicitAddressWithAlias
has an Ord
instance.
Note: this "merely" needs to be consistent, but it can be arbitrary (as there is no proper way to compare these).
