Changes
Major
- implemented `Solution.infeasible` property that tries to understand whether the solver returned an infeasible status
- implemented `csnlp.util.math.norm_1` and `norm_inf` for easier conversion of these norms to linear programmes
- converted `Mpc.set_linear_dynamics` to the more general `set_affine_dynamics`
- added single and multiple shooting affine time-varying dynamics in `PwaMpc`, allowing users to specify a switching sequence and solving a simpler quadratic programme, instead of optimizing also over the sequence of regions
Minor
- added `solver_plugin` property to `Solution`, so that one can retrieve the solver used to compute a solution to an optimization problem
- fixed bug with optimization problems with a single scalar discrete variable
- fixed bug in `ScenarioMpc` where single slack variables were not properly substituted
- better docstrings
- updated CI
