Create second scalability factor column in components.csv file

Currently the scalability of the warm water profiles (thermal demand) is read as the last parameter of a subtype if this line in the agent_creator method (Model) is not commented. A second column containing the scaling factor of the second profile should be added to the subtypes in the components.csv file. This affects also the https://git.rwth-aachen.de/acs/research/swarmgrid/scenariogenerator project as the column containing S_r will be shifted to the right by one column through this.
