At the moment, we tell CVODE to estimate the Jacobian. We know that providing our own computation makes time integration work more efficiently.

As example fidimag/examples/micromagnetic/nmag_example_2_box/sim.py (not a test yet because it fails) shows, the computation hangs somewhere.

Need to fix this.

This problem is running now with the new Sundials upgrade, but the diagonal and Jacobian precond methods, run super slow
