This bootstraps the remote agent from Rust so that we have access to write to stderr using the eprintln!() macro. There is a future intention to expand Rust usage in the remote agent by delegating CDP and WebDriver Bi-Di protocol schema validation to serde. The Rust port is faithful to the JS version in terms of functionality, and in some places improves on the original design by enforcing a strict division between flag handling code on one hand, and the remote agent server on the other.
