Must be implemented, must not throw a PropertyNotImplementedException.
AtPark is True when the telescope is in the parked state. This is achieved by calling the Park()()()() method. When AtPark is true, the telescope movement is stopped (or restricted to a small safe range of movement) and all calls that would cause telescope movement (e.g. slewing, changing Tracking state) must not do so, and must raise an error.
The telescope is taken out of parked state by calling the Unpark()()()() method. If the telescope cannot be parked, then AtPark must always return False.
This is only available for telescope InterfaceVersions 2 and 3
