Research direction

Start by reading the existing .lanes() and .axis_iter() entry points and how they produce arrays or views. Work out the API for selecting K axes and returning (D-K)-dimensional ArrayViews suitable for Zip, then add coverage showing the 2-D and 4-D projection use case works.

Description

enhancement help wanted

Now we have .lanes() which returns (D-1)-dim NdProducer of 1-dim arrays
and .axis_iter() which returns 1-dim NdProducer of (D-1)-dim arrays
Anything in between?
Say, I want to Zip 2-D array and projection of 4-D array, how do I facilitate that?
