Additional context

Fixes #242 . I first looked at how SimpleNonlinearSolve.jl does this and basically came up with the most simple solution to match. I also bumped the SciMLBase.jl version since otherwise some disallowed solver kwargs, like nout and batch, could potentially cause errors. (This scenario would be unlikely, i.e. someone mixing the old nout/batch interface with the new IntegralFunction interface, but I would rather avoid any errors if possible, which SciML/SciMLBase.jl#609 helped with by making it impossible for nout/batch to get stored as prob.kwargs.)
