SGP/SEBS/E37 - Surface energy balance incorrect

Soil temperature 3 was incorrect, therefore the surface energy balance was incorrect.

• Soil temperature mean 3(soil_temp_3)
• Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
• Soil heat capacity 3(soil_heat_capacity_3)
• Change in energy storage 3, 0-5 cm soil layer(energy_storage_change_3)
• Surface energy balance(surface_energy_balance)
