Length based pipeline efficiency

[Eric-Nitschke]

!!!Not tested yet, don't review!!!

Closes #1213.

Changes proposed in this Pull Request

Major changes:

• change the efficiency of H2 pipelines from a static value (that is somewhat faulty see BR Hydrogen pipeline efficiency #1213) to a length based calculation similar to PyPSA-Eur in scripts/add_extra_components.py.

Minor changes:

• override the networks component attributes in scripts/add_extra_components.py and scripts/solve_network.py to accomodate the length based efficiencies.
• add the transmission efficiencies of H2 pipelines to the config.
