VisIt doesn't handle the case where scripts have arguments named the same as VisIt arguments

[JustinPrivitera]

Taken from a conversation with a user:

#!/usr/bin/env python3
import argparse
import visit # type: ignore

def cli_args() -> argparse.Namespace:
    parser = argparse.ArgumentParser()
    parser.add_argument('-nn', type=int)
    #parser.add_argument('-nodes', type=int)
    return parser.parse_args(visit.Argv())

def main():
    print(cli_args())

main()
exit()

so if you do visit -nowin -cli -s test.py -nn 1 you'll get an error but if you comment out the -nn and uncomment the -nodes in cli_args and then run visit -nowin -cli -s test.py -nodes 1 then it works

What are our thoughts on this? Should we support this case? At the very least it's a pitfall users can run into.
