Rename project wg2sd -> wg2nd, new CLI + generate

1. Renamed the project from wg2sd to wg2nd
2. Modified the _gen_netdev_cfg() function to handle the MTUBytes field.
3. Add new CLI with `generate` and `install` commands
4. Modified the gen_systemd_config() function to accept keyfile_or_output_path and filename parameters.
   - user can choose the name of the keyfile on the CLI
   - user can choose alternative output filename (instead of just using
     the  interface name)
