`DataSet.vectors` does not work with cell data

See original GitHub issue

Describe the bug, what’s wrong, and what you expect:

DataSet.vectors does not work with cell data as it adds to DataSet.point_arrays.

This is easily fixed, but I would be in favor of totally deprecating this functionality as it duplicates the DataSet["my_vector_name"] = data functionality. It is confusing to me why there is a special method here. It was also confusing in https://github.com/pyvista/pyvista-support/issues/448 and partially in https://github.com/pyvista/pyvista-support/issues/438.

To Reproduce

Please include a code snippet to reproduce the bug in the block below:

mesh = pv.Plane()
mesh.vectors = np.ones([mesh.n_cells, 3])

We need a way of exposing VTK’s SetVectors within our APIs and need to open a specific issue for that.

I think #1431 should suffice for that. Lets continue moving that piece of the conversation there.

Yes! Thank you. I did mean #1431, and I agree that the information is best continued there (I didn’t realize at the time it had been transferred). I will edit my comment with the correct issue number, and try to clean things up a bit. I’ll also post my current work around in #1431.
