feat: Add WireGuard client

- Add a WireGuard client to the project.
- New utility functions have been added to parse the output of `wg show` command and improve error handling.
- Add start, down, show, show_config, generate_private_key, and get_public_key method to interact with the wg binary.
- Created a new example file to offer more clear usage.
