Script helper for making README entries with literal spacing from help text

[ZLLentz]

The readme table in this repo is kind of tough to get the formatting correct in, it normally removes all extra spacing giving strange looking results.

In ioc-deploy I found a reasonably simple way to create a text blob that would format as a literal in the html table, and I did it manually for a while before writing a small helper for it , print_help_text_for_readme.

The idea of this ticket would be something like

ioc-deploy --help | readme-ify

I think using help text output in general for the readme is really common even if not everything uses argparse
