The information about nf is not utilized when generating the info files. This PR fixes that.
evolven3fit relies on eko for the info file so once this is merged into a release of eko it should work fine.

Apparently LHAPDF doesn't have a block mechanism for alpha_s so at the moment we just provide two values for two nfs for the same Q at the thresholds.

(As far as I can see, the same problem was there in NNPDF4.0 -apfel + evolven3fit- and NNPDF3.1 -apfel + evolvennfit-, so nobody ever noticed...)

PS: it would have been more convenient to discuss here instead of the commit 🙈

I'm now relying on the passed opcard and we better hope that the opcard which is given as argument and the EKO are compatible (i.e. they have the same scales), something we don't explicitly check ...

I guess this is fine unless you give a wrapper that does the full thing. But given that the info file generation is its own thing it makes sense to allow for extra flexibility

(sorry for commenting in the commit, I just followed the link in the email and didn't pay attention :___ )

I just rerun this after your changes (with the same eko from before) and seems to work the same
