docs: getSubscriptionResults(string) -> dict(integer: <value_type>)
  
          Returns the subscription results for the last time step and the given object.
          If no object id is given, all subscription results are returned in a dict.
          If the object id is unknown or the subscription did for any reason return no data,
          'None' is returned.
          It is not possible to retrieve older subscription results than the ones
          from the last time step.
