* Bugfix: Adjusted efficiency2 (to atmosphere) for bioliquids-to-oil Link in `prepare_sector_network` to exactly offset the corresponding oil emissions.

* Bugfix: Waste CHPs were added to all electricity buses even if they were not connected to heating network. This is now fixed.

* Bugfix: Duplicates in build_transmission_projects were caught, but not removed from the network. This is now fixed.

* Replaced the Store representation of biogenic carriers (solid biomass, biogas, bioliquids, MSW) in ``prepare_sector_network`` with the extended Generator component that uses the ``e_sum_min`` and ``e_sum_max`` attributes to enforce minimum usage and limit maximum potential, respectively.
