Timedelta.resolution used to return a string, but that was deprecated in 0.25.0. Enforce that deprecation to return Timedelta(nanoseconds=1), mirroring the stdlib timedelta.resolution behavior.

Timestamp.resolution correctly mirrors datetime.resolution by returning Timedelta(nanoseconds=1), but it is a property whereas for the stdlib it is a class attribute. This PR makes it a class attribute for Timestamp.

Think a newline is needed here.
