The old name was misleading because this struct is designed to iterate over any axis, not just the outermost axis.
This replaces these free functions with `new` methods on `AxisIter` and `AxisIterMut`.
Removing the macro makes the code easier to understand without being much more verbose.
It's simpler to treat `Baseiter` as just an iterator over pointers, with no lifetime information. Lifetimes should be handled as necessary by the wrappers around `Baseiter`.

This PR does the following:
Removes lots of iterator constructor functions and replaces them with
newmethods on the iterators. This is more conventional, easier to understand, and requires fewer imports.Renames
OuterIterCoretoAxisIterCoreto better reflect its purpose.Refactors
.split_at()forAxisIterandAxisIterMutto eliminate theaxis_iter_split_at_impl!macro.Removes the lifetime from
Baseiterand implements iterator traits forBaseiter. This is mostly a conceptual simplification. It will also make it more straightforward to extend the iterators toArrayPtr/ArrayPtrMutin Add raw array pointer types #496.Improve docs and implement
