Constraints and dual variables

[ocots]

@PierreMartinon When you build the solution:

https://github.com/control-toolbox/CTDirect.jl/blob/7651fab799cb56df85f4a99768b2d820d2f6c39a/src/solution.jl#L41C1-L56C6

Is path_constraints_dual ordered like CTModels.boundary_constraints_nl(docp.ocp)[2]? Same question for all the other constraints.

I ask the question since I am plotting the constraints and the dual variables: control-toolbox/CTModels.jl#53.
