How to create a PyArray4?

[BrosnanYuen]

How do you create a numpy::array::PyArray4 from rust vectors?

There isn't a from_vec4 function

While the from_vec* are convenient, they are also a relatively inefficient way to construct n-dimensional vectors and hence we do only provide them for low-dimensionality cases and mainly for testing and experimentation.

In general and in particular for the high-dimensionality cases, the intended way to produce an ndarray::Array and then convert this into a PyArray using e.g. the IntoPyArray trait.
