Research direction

Start by locating SliceOrIndex and the ndarray slicing macros, then inspect how slice values are converted into array indices. Define the iterator's expected output and behavior for the FFI use case, with completion demonstrated by iteration producing the actual index values needed by the C API.

Written by the indexing model from the issue text.

Description

It would be handy to be able to iterate over a SliceOrIndex to be able to get actual array indices.

My current use case for this is to be able to re-use ndarray's slicing macros in wrapping an FFI module (the C API requires an array of index values to be passed in).
