`edit` subcommand cannot remove options

[cab404]

I don't really know, how to implement removal in command line, though. Like wgbond edit test ~gateway ~masquerade? Not sure clap supports that.

Maybe add something like crontab -e.

Also, stuff like https://pauljuliusmartinez.github.io/ looks super cool, but is a product on it's own I guess.
