    Set safe version of hacking
    
    Versions of hacking from 3.1.0 until 4.0.0 NOT included are supposed
    to require a safe version of flake8, so besides normale issues related
    to minor version upgrades, we can safely use those versions.
    Also forcing pycodestyle versions to be compatible with flake8 installed
    by hacking.
