Numpy 2.4.0 release breaks wavelength calibration

[bmiszalski]

Hi all,
Just to let you know that after updating a Docker image I use to run the pipeline, I came across this error under Python 3.11 that breaks the wavelength calibration step. I also got a similar one with Python 13.3.

It turns out the culprit is numpy 2.4.0. Downgrading to numpy 2.3.0 resolved this issue, but it may be a good idea to understand this going forward so a fix can be incorporated.

Best regards,
Brent.
