Flow implementation
Hi,
Here is the implementation of the correction with normalizing flows for HiggsDNA. I already implemented it for the 3 (tn,zmmg and diphoton) processors.
Regarding the pytorch and zuko dependencies, instead of putting it in the "main" environment file, I added the flow_enviroment.yml file that contains the additional pytorch and zuko dependencies. So ones has to update the Higgs-dna environment conda env update --file flow_enviroment.yml
in order to run the flow corrections
