HFG to HOG migration
This is to mainly switch the generator from hfg to hog #4 (closed). As we want to add and correct the available forms, it would be helpful if the repository uses hog.
The main changes are in generate.py, requirements.txt and .gitlab-ci.yml, then all the operators are regenerated with hog.
