PyPhaseDiagram.to_dict now compares pressures of both phases. If they are different (e.g. when PyPhaseDiagram.spinodal was used as constructor), pressures for both phases are stored ("pressure liquid", "pressure vapor").
Added PyStateVec.to_dict method that calculates the same properties as PyPhaseDiagram.to_dict for the states stored in PyStateVec.
