Add support for adding multiple clients (#58)
This commit puts the client creation logic into a function. By running the script followed by `add_client`, the user will be asked a few questions and a new peer will be added. Removing client is **not** supported. The client files have random names. Fix for https://github.com/angristan/wireguard-install/issues/3
