The gen_header.py script is failing for older versions of python3 such as python 3.5. Two issues observed with python 3.5 are ... 1. Python 3 versions prior to 3.6 do not support the f-string format. 2. Early python 3 versions do not support the 'required' argument for the argparse add_subparsers(). Fix both of the above so that older versions of python 3 still work.
