Breaking changes

Features

- Network data:
- expose "slack terminal" extension (414)
- expose coordinatedReactiveControl extension (556)
- bus_id in busbar sections dataframe (525)
- expose network elements aliases (531)
- add new dataframes for identifiables, injections, branches and terminals (527)

the results status are the same as before except for postContingencyResults status that can be NO_IMPACT, meaning the contingency had no impact on the network (536)
