Add co2 capture in industry transformation when coupled to CTM.

[robindesmit-quintel]

Context

When the CTM is coupled to the ETM, the ETM shows more detailed sliders under Emissions > CCUS. This section should also include sliders to adjust the share of CO₂ captured from industry transformation emissions.

Implemented changes

Remove the old Generic industry slider and create 3 new sliders:

• co2 captured from emissions of fertilisers (in share)
• co2 captured from emissions of refineries (in share)
• co2 captured from emissions of chemicals (in share)
  Update the labels in sliders, header, and graphs.

When I have one of the external coupling groups of the transformation nodes inactive, e.g. industry_chemical_refineries, the other two sliders that are active do not appear in the front-end. See screenshots:

I think that if an interface_group only contains external coupling sliders and if one is inactive, the other sliders also don't show. Therefore, I think it's best to after all put the sliders under the interface groups of the relevant sector. So the refineries input under "Industry refineries", chemicals under "Industry chemical" and fertilizers under "Industry fertilizers (process emissions)". Put the below the existing sliders and rename them "Captured CO2 from emissions from transformation".

Please do a final check with @mabijkerk to see if he agrees.

You can then also remove the interface_group external_coupling_industry_transformations_ccus and its remnants.

@kndehaan we solved this by keeping the coupling group to ccus. Ideally we would have indeed added these new inputs to the coupling groups of their respective sectors, but in the migration it turned out that there were scenarios with only ccus coupled. If we would have added these inputs to these other groups, those scenarios would no longer have CO2 capture.

Final thought is that these capture sliders (and the corresponding emission inputs) do not affect primary emissions in any way. This is correct, but it still can be confusing for users. Should we mention something about it in the slider texts you think @robindesmit-quintel?
