[Bug]: Limit max iterations not working on SciPy optimisers

[BradyPlanden]

Python Version

3.11

Describe the bug

The SciPy solvers aren't passed optim.set_max_iterations() correctly at the moment, this is fixed in #224.

Steps to reproduce the behaviour

    @pytest.mark.unit
    def test_infeasible_solutions(self, cost):
        # Test infeasible solutions
        for optimiser in [pybop.SciPyMinimize, pybop.GradientDescent]:
            optim = pybop.Optimisation(
                cost=cost, optimiser=optimiser, allow_infeasible_solutions=False
            )
            optim.set_max_iterations(1)
            optim.run()
            assert optim._iterations == 1

stochastically returns values > 1
