Move calcualtion of CCS emission factors to build cost data

[trevorb1]

Feature Request

The sector coupling side relies on using emission factor data from the costs.csv file. Having the calculation of emission factor CCS techs in add_extra_components.py means the calculation of emission factors is repeated in sector side.

It would probably make sense to do the calculation of CCS emission factors in build_cost_data to allow for downstream use.
