10x - 100x speed up when using own implementation of Implicit Euler or Implicit Midpoint on linear test problem

This is the result of running ```julia # profiling solver = KrylovJL_GMRES(); # my implicit euler @profview for i in 1:500 my_implicit_euler(prob_op, dt, solver); end # ImplicitEuler @profview for i...

10x - 100x speed up when using own implementation of Implicit Euler or Implicit Midpoint on linear test problem

Note sure if this is relevant/related, but the same performance different can be seen using ``KrylovJL_BICGSTAB()`` for example. And ``KrylovJL_CG()`` gives an warning when using ``ImplicitEuler(linsolve = KrylovJL_CG())`` ```julia ┌...

Improve error on Enzyme inability to differentiate

> That should throw a better error.... I just had a similar problem (when not using Enzyme), where I also forgot to include the ``ndrange`` and got the following error:...
