None not allowed in the position argument of i3.Place

The arguments for i3.Place have been made stricter and streamlined with other Place specs. Now the following syntax will result in an error: i3.Place(“my_cell”, position=(10, None)). The error will mention that you should use i3.Place.X or i3.Place.Y, depending on your case.
