Negative generated emission rates are set to zero during write_power_sector_results
Negative consumed emission rates were bugs, these were fixed by:
fixing the incorrect sign on interchange during calculation of net_consumed_mwh
using EIA-930 demand instead of net_consumed_mwh for BAs with inconsistencies between EIA-930 interchange and our net_generation_mwh, because these inconsistencies prevent calculation of a reasonable net_consumed_mwh
Add rate columns to validation check for negative values
Add running of validation check to output_to_results to guarantee that all result files must pass validation check
