Fix the electricity and heat consumption of carbon capture in industry

At the moment the energy demand for carbon capture for process heat from gas and solid biomass is simply modelled as a 10% loss of energy:

Carbon capture from process emissions involves no energy use:

There are assumptions for carbon capture electricity and heat demand for post-combustion capture on cement kilns we can use, but it involves disaggregating the carbon capture and carbon management to each node, so that we can attach to the heat and electricity buses at each node.

Start in scripts/prepare_sector_network.py at the linked lines 1531, 1567, and 1704 to trace how carbon capture energy demand and carbon management are modelled. Review the existing cement kiln post-combustion capture assumptions and how heat and electricity buses are connected at each node. Done means the gas, solid biomass, and process-emission cases use the intended electricity and heat demands without losing node-level connections.
