ENH: use sparse meshgrid instead of indices().tolist()
tolist() converts numpy integers to python integers which are converted
back to numpy integers by the indexing.
meshgrid(indexing='ij') returns the indices wanted here as the right type.
triples performance of sorting a size=(200, 200, 50) array along axis 2
and reduces memory usage by almost 40%.
