Support headless servers with protonvpn-cli
Please support headless servers with protonvpn-cli. Any command line program that requires a desktop environment is not a proper command line program. It would also be nice if it could generate a systemd service configuration to allow startup at boot with preconfigured settings. I would guess the primary application for this program is to run on a Raspberry PI or other unattended server without a monitor or a desktop, so this is a crucial requirement.
