staggered boundary generation: direction index should point to fluid cell when inner_or_boundary=False

In that case, the index vector contains the boundary cells, so the direction should point to the fluid cell.
When inner_or_boundary=True, the index vector contains the fluid cells and the direction points to the boundary cell.

274e09cd introduced a skip of the generation if the target file is not
present. While this might hint a wrong target directory it also prevents the
generation of new files. Since the provided mesa_pd.py script asks to
confirm the target directory anyway, this skip is removed.
