 - [ ] New low-level interfaces are introduced, that fit the SciML-ecosystem. For example, a FMU can still be simulated with `simulate(fmu)`, but one can also decide to create a `prob = FMUProblem(fmu)` (like an `ODEProblem`) and use `solve(prob)` to obtain a solution. Keywords will be adapted to have a fully consistent interface with the remaining SciML-ecosystem.
