Included geothermal energy in the final demand steam hot water query from the energy balance. (The households_final_demand_steam_hot_water and buildings_final_demand_steam_hot_water nodes receive energy from both CHPs and the collective_geothermal plant. This geothermal energy should therefore also be queries from the energy balance because this is reported in a seperate column.
Added encrypted energy balances.
Update Refinery to special-case zero-demand slots
