The Issue

The global opts like Co2L currently are missing the logic to update the config based on the settings in the scenario configuration. This is due to the update of pypsa-eur's prepare_network rule which looks for those enable field when setting CO2 limits.

We should update the configuration files based on the scenario Opts.
