It has been noted over the last six to eight months that some versions of Numpy have issues with the klipper python environment on some machines. This PR introduces a fixed version that is known to work and a small test for people to do to make sure there are no output issues from the get go. These have been pulled from the pinned posts in the discord, from a time when 1.26 was causing issue, and now it seems v2 is also having some issues, hence the change.
