Feat: Fail on unrecognized option.

[garronej]

Hello again,

It would be nice to have an option to exit with an error code and a message when there are options proided that aren't known.

For example if an user make a typo and type --slient instead of --silent I would like to be able to let them know.

Hello @garronej 👋 ,
First of all, thanks for all your contributions and opened issues 🤗 .
Indeed, it has not been implemented yet: a strict opt-in option could be a way to enable such a need 👍 .
If you've already an implementation idea in mind, feel free to contribute, otherwise, I will try to prioritize it.
