docs: Instantiate a new GuaranteedStopLossOrderLevelRestriction from a dict
          (generally from loading a JSON response). The data used to instantiate
          the GuaranteedStopLossOrderLevelRestriction is a shallow copy of the
          dict passed in, with any complex child types instantiated
          appropriately.
