add NNPDF40 hyperopt runcard
Created by: RoyStegeman
For the sake of being complete and enabling people to run their own hyperopts, I thought it would be good to also add a hyperopt runcard with the specific reduced dataset and K-folds used to determine the NNPDF4.0 setup.
Also, many runcards still contained # Configuration file for NNPDF++
, which this PR replaces with # Configuration file for n3fit
.
