CVODE and IDA have been interfaced and many common features have been factorized
in the OdeManager class. However, ARKODE (various modern explicit, implicit and
mixed explicit/implicit Runge-Kutta solvers) does not exist in the old 2.4.0
version of Sundials which is used in Scilab hence won't be interfaced unless an
upgrade is done (Sundials is now at version 5.7.0). The support of Sparse
Jacobians is also missing for the same reason.
