Draft: Hotfix NN models before they are picked up in data taking
Hotfixes models intrudced in lhcb/Allen!1634 (merged) .
The fix goes down to a technicality about Lipschitz NNs (https://arxiv.org/abs/2112.00038) . The normalisation was not rigorously imposed, thus the robustness was not ensured via the Lipschitz constant.
These changes accomplish marginally better performance + the the afore-mentioned robustness.
