[vtkusers] SetCells for multiple cell types

[Nico Schlömer]

Thanks for the suggestion!
I actually ended up implementing it without the `UnstructuredGridSource`
and just a plain old `vtkUnstructuredGrid`:
```
    mesh.SetCells(
        numpy_support.numpy_to_vtk(
            cell_types,
            deep=1,
            array_type=vtk.vtkUnsignedCharArray().GetDataType()
            ),
        numpy_support.numpy_to_vtk(
            cell_offsets,
            deep=1,
            array_type=vtk.vtkIdTypeArray().GetDataType()
            ),
        cell_array
        )
```

Cheers,
Nico
