Simplify development and maintenance immensely by making this a monorepository: - Convert PassepartoutKit and VPN bindings to local packages - OpenVPN/OpenSSL - WireGuard/Go - Make PassepartoutKit available via - Source submodule for production (private) - [Binary XCFramework for development](https://github.com/passepartoutvpn/passepartoutkit) - Add PassepartoutKit Demo in root - Deploy package later
