fix(model): Remove north from Model properties

After some discussions with @mostaphaRoudsari , we have decided that the north should not be a property of the Model for the same reason why we don't have the location as a part of the model. The north direction is a property of the simulation assets like the skies used in Radiance or the simulation parameters used in our EnergyPlus.
