Research direction

Start with the linked parallel axis-iterators documentation and the existing map_axis API. Determine how a parallel axis-mapping operation could avoid collecting into a Vec while preserving compatibility with subsequent ndarray operations; done means the proposed behavior is implemented and covered by relevant tests.

Written by the indexing model from the issue text.

Description

The documentation recommends collecting into a Vec when performing parallel axis operations, https://docs.rs/ndarray/0.15.4/ndarray/parallel/index.html#axis-iterators. This is far from ideal when further ndarray operations are required. It would be helpful if axis could be mapped in parallel like how map_axis maps sequentially.
