Update numpy dependency

[qacwnfq]

Dear Cobra-Team

I noticed that cobra 0.26.3 depends on numpy<1.24 and >=1.13.
With more and more packages moving to numpy>=1.24 I suggest updating this dependency.

The incompatible right now is, that np.float64 and some other numpy types were removed.
The cobra code would have to be checked and the removed types would have to be replaced by suitable ones.

I hereby confirm that I have:

• Tried to solve the issue on my own
• Retried to run my code with the latest version of The COBRA Toolbox
• Checked that a similar issue has not already been opened
