Numpy upper limit: <2.0.0

[LinasKo]

Description

As of a few days ago, an error is raised when attempting to load cv2, as it does not support numpy 2.0.0. This results in our CI tests failing and may have consequences for end-users.

Until all our dependencies expand support, let's pin numpy to <2.0.0.

I have not done anything with respect to versioning. We should think about releasing this as 0.21.1.

I think it's a good decision to merge quickly this time; thanks @onuralpszr!

Though for anything larger (even if urgent), let's add some time for a core team to get a second opinion 😉

Thanks, For this one. I had to make sure dev is alive and for actual solution we need to find abi friendly way handling it for 1.x and 2.x if possible
