How to use the interface.pulser_interface.PulserConstraints function in Interface

PulserConstraints class.

        Each scalar parameter is an ScalarConstraints object defined in cor.util.interfaces.
        Essentially it contains min/max values as well as min step size, default value and unit of
        the parameter.

        PulserConstraints.activation_config differs, since it contain the channel
        configuration/activation information of the form:
            {: ,
             : ,
             ...}

        If the constraints cannot be set in the pulsing hardware (e.g. because it might have no
        sequence mode) just leave it out so that the default is used (only zeros).
