NNPDF/nnpdf: 4.1.2

Another minor release towards 4.1 In this release MHOU becomes the default and new positivity constraints are added to the commondata and runcard. Fits are now done by default in the diagonal basis (it can be deactivated with diagonal_basis: False), this means that the full covariance matrix gets diagonalized and training/validation split is done at the level of the entire dataset entering the fit. What's Changed Add N3LO pch theories by @giacomomagni in https://github.com/NNPDF/nnpdf/pull/2366 Adding tool to shift theoretical predictions due to correlated exp errors in data/theory comparison plots by default and a fallback for those in which it cannot be computed #2357 #2402 Using Stats for sumrule statistics #2386 Inconsistent closure test routines are added to the main repository #2272 #2277 Add the possibility of adding extra data folders with the data_path variable. #2384 Disable tensorfloat32 type in hardware that support it #2404 Make the diagonal fit the default by #2359 Full Changelog: https://github.com/NNPDF/nnpdf/compare/4.1.1...4.1.2
