SGP/EBBR/E35 - Sensible and latent heat fluxes intermittently incorrect

Soil heat flow #5 was sometimes incorrect; sensible and latent heat flow were therefore 
sometimes incorrect also.

• Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
• Surface soil heat flux 5(surface_soil_heat_flux_5)
• Soil heat flow 5(soil_heat_flow_5)
• Soil heat flow 5, corrected for soil moisture(corr_soil_heat_flow_5)
• Surface latent heat flux(latent_heat_flux)
• Surface sensible heat flux(sensible_heat_flux)
