Authentication

[Paddy-NI]

Hello thank you for your wonderful script.

I have a small issue though. I have enabled authentication via https://docs.ntfy.sh/config/#example-private-instance

So a message gets sent with "curl -u user:password" and was wondering if this could be added to your project?

Perhaps "/set ntfy_auth user:password" might be used in addition to "/set ntfy_endpoint https://ntfy.example.com/irssi"?

Sorry for the late reply. I currently use IRC through Element (Matrix), which has push notifications, so I haven't needed ntfy. Still, I might try it again since I also use irssi. It's not too difficult to add, though. In the meantime, PRs are welcome.
