lbmpy 0.4.0 not working with pystenicls 0.3.4
I am getting

when using `lbmpy` 0.4.0 and `pystenicls` 0.3.4. After updating to `pystenicls` 0.4.0 everything works again.
I guess `lbmpy` 0.4.0 needs to have `pystencils` 0.4.0 as a dependency and not just any `pystencils`.
Currently, the setup.py just says `pystencils`
