PyPSA/technology-data: Technology Data Version 0.2.0

See the full release notes at: https://technology-data.readthedocs.io/en/latest/release_notes.html#technology-data-0-2-0-11th-december-2020 This release allows to include uncertainty bounds from the Danish Energy Agency (DEA), fixes inconsistencies with the handling of combined heat and power plants, and includes the latest data from the DEA on carbon capture technologies. It is released to coincide with PyPSA-Eur Version 0.3.0 and PyPSA-Eur-Sec Version 0.4.0, and is known to work with these releases. Features in more detail: Using the expectation parameter in config.yaml you can control whether the upper and lower uncertainty bounds on technology parameters are read in from the DEA datasets. The biomass and gas combined heat and power (CHP) parameters c_v and c_b were read in assuming they were extraction plants rather than back pressure plants. The data is now corrected and they are implemented in PyPSA-Eur-Sec Version 0.4.0 with a fixed ratio of electricity to heat output. The old assumptions underestimated the heat output. The updated assumptions from the DEA for carbon capture technologies have been incorporated, including direct air capture and post-combustion capture on CHPs, cement kilns and other industrial facilities. These are then used in PyPSA-Eur-Sec Version 0.4.0
