Pass dimensions as an array

[wkearn]

I merged TopoToolbox/libtopotoolbox#69, which changes the libtopotoolbox API to take a ptrdiff_t dims[2] instead of two separate arguments nrows and ncols. We should update the pytopotoolbox bindings accordingly.

For row-major arrays, one would create ptrdiff_t dims[2] = {ncols,nrows}, while for column-major arrays one uses ptrdiff_t dims[2] = {nrows,ncols}.

Ideally we would be able to pass the dimensions in the correct order and then skip the reordering steps that we introduced in #51.

I am not sure if it makes more sense to create the dims object in Python and pass it to the C++ binding or if we should pass the dimensions separately along with some kind of row/column major flag to the C++ binding and organize the dims array there.

This change will show up in the 2024-W31 release of libtopotoolbox on 29-07-2024.
