After refactoring, we propose to implement the DC sensitivity analysis as follows:

Calculation of potential/actual connecrtivity losses of the contingencies (for now, in the WoodburyEngine).
Calculation of rhs (for flows/injections), with modifications applied to the rhs in cases of broken connectivity, glsk with loss of elements... This is done in the DcSensitivityAnalysis class, and modified rhs are stored in the class WoodburyEngineRhsModifications.
Calculation of pre/post contingency states using the WoodburyEngine. Note that only states are calculated here.
Calculation of sensitivities in the DcSensitivityAnalysis class from the previously calculated states, and filling writers/results returned by the DC sensitivity analysis.
