Cannot load SMAC3v2 runs if parameter values are not hashable

[JonasHanselle]

I was trying to load a SMAC3v2 run where one of the categorical parameters was a list:
{"type": "categorical", "name": "score_set", "choices": [[-3, -2, -1, 1, 2, 3], [-2, -1, 1, 2]], "weights": null, "default_value": [-3, -2, -1, 1, 2, 3], "meta": null}

DeepCave was not able to load the run, giving the following Warning: "RunHandler (WARNING): SMAC3v2: unhashable type: 'list'."

Is this behavior intended?
