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.

Lines 36 to 43 in dc60111

	if any("CCS" in carrier for carrier in carriers):
	ccs_carriers = [carrier for carrier in carriers if "CCS" in carrier]
	for ccs_carrier in ccs_carriers:
	base_carrier = ccs_carrier.split("-")[0]
	base_emissions = n.carriers.loc[base_carrier, "co2_emissions"]
	ccs_level = int(ccs_carrier.split("-")[1].replace("CCS", ""))
	ccs_emissions = (1 - ccs_level / 100) * base_emissions
	n.carriers.loc[ccs_carrier, "co2_emissions"] = ccs_emissions
