    Imports, caches and returns the ROOT module and sets certain flags when it was not already
    cached. When *batch* is *True*, the module is loaded in batch mode. When *ignore_cli* is *True*,
    ROOT's command line parsing is disabled. When *reset* is *True*, the two settings are enforced
    independent of whether the module was previously cached or not. This entails enabling them in
    case they were disabled before.
