Describe the Bug

Currently, data/costs.scv file is out of sink with the model and must be updated to match the requirements of the sector-coupled version. As an example, parameters of Fischer-Tropsch are missed while they are requested by prepare_sector_network.

Thanks a lot @apigott for spotting it!

A way to fix is to retrieve the costs data by running retrieve_cost_data and update the git-tracked data/costs.csv accordingly
