New CSA-profiles CRAC importer

This importer respects the ENTSO-E specification for CIM CSA-profiles v2.2.
For now, supported objects are:

• Contingencies
• Flow CNECs
• Topological remedial actions (only opening switches for now, and only on-instant & on-contingency-instant usage rules)
• Injection set-point remedial actions (only on-instant & on-contingency-instant usage rules)
• PST range actions (only on-instant & on-contingency-instant usage rules)

CIM CRAC importer

• The importer is now more permissive on where it should find contingencies & flow CNECs. Read about it here: #784

Remedial action optimisation

• The RAO is now faster thanks to an optimisation of the search-tree algorithm. Read about it here: #766
• A minor bug has been fixed inside the search-tree: #778
• Misc issues with automaton simulation have also been fixed: #777

CRAC API

• It is now possible to define remedial actions that are available after a constraint on a voltage CNEC. Read about it here: #775

Full Changelog: v4.2.6...v4.3.0

v4.2.4.1

Correct a bug in max-cra-per-tso where all range actions were counted (not only the ones belonging to TSO)

v4.2.6

What's Changed

• Demote some logs by @pet-mit in #739
• Refacto parameters by @Godelaine in #736
  BREAKING CHANGE : Rao parameters must be refactored. curative-rao-optimize-operators-not-sharing-cras is reversed. LoopFlow, MNEC and RelativeMargins parameters are now RaoParameters extensions.
• BUG FIX : FaraoException thrown with diverging perimeter by @Godelaine in #741

Full Changelog: v4.2.5...v4.2.6

v4.2.5

What's Changed

• Improve AUTO CNECs optimization by @pet-mit in #726
  BREAKING CHANGE If AUTO CNECs exist with no associated AUTO RAs, these CNECs are duplicated in the OUTAGE instant in order to be secured by the preventive RAO. Implemented for the CIM CRAC creator.
• Fix hvdc setpoint by @pet-mit in #723
  BREAKING CHANGE When disabling AC emulation on an HVDC, its original (AC-emulation) set-point has to be computed and set before running sensitivity analysis, in order to ensure convergence
• Reason per perimeter2 by @Godelaine in #710
  BREAKING CHANGE The RAO can now detect & isolate contingency perimeters that diverge
• Second prev info in rao result by @MartinBelthle in #711
  The RaoResult object can now tell which RAO steps have been executed
• More optimal approach to max CRA by @pet-mit in #730
  BREAKING CHANGE When limited by a maximum number of CRAs, the RAO can now choose a range action or a network action to optimize the minimum margin (whereas it priviliged range actions before)
• Bump powsybl and its dependencies versions by @phiedw in #731
  PowSyBl version bump
• Consider ARAs in 2P by @Godelaine in #728
  BREAKING CHANGE Second preventive RAO now behaves a lot better when mixed with AUTO perimeters
• Add messages to CNE exceptions by @pet-mit in #732
  Bug fix
• Reduces amount of calls to getFunctionalCost method by @MartinBelthle in #729
