Check md5 integrity against vp-setupfit in n3fit

[achiefa]

This PR should address #2461. Please have a look.

Also, I was wondering whether we want to hash also the files in filter directory. This would be an easy fix.

[achiefa]

I think I'm done with this. Can you please check so that we can merge it into Jaco's PR?

[achiefa]

I tested this and it works fine. Should I remove the hashing of the theorycovamat?

Should I remove the hashing of the theorycovamat?

Yes, since we are not going to recompute the theorycovmat when running n3fit.

[achiefa]

Hi @scarlehoff, I've implemented your suggestions. Let me know.

[scarlehoff]

I think you can rebase only the md5 part on top of master (instead of pointing to diag_covmat_reproducibility) and we merge this by itself.
It's mostly orthogonal and it can be useful already I would say.

[achiefa]

Yes, I agree. I've reversed the changes inherited from diag_covmat_reproducibility. Now this points to master. Once the tests finish, we can merge this.

Edit: let me rebase on top of master before

[achiefa]

Rebased on top of master

I've updated the tests, and the documentation as well. The tests are now running. Can you please check if this is what you had in mind?

[scarlehoff]

Thanks! And thanks for updating the docs as well.
