TL;DR

Added CI/CD workflow for Rust and updated README with benchmark results.

What changed?

• Introduced a new GitHub Actions workflow for Rust (.github/workflows/rust.yml)
• Added a CI/CD badge to the README
• Included benchmark results comparing nyx-ψ, TCP, and UDP performance under various packet loss scenarios

How to test?

1. Check the GitHub Actions tab to ensure the Rust workflow is running correctly on push and pull requests to the main branch
2. Verify the CI/CD badge is displaying correctly in the README
3. Review the benchmark results table in the README for accuracy

Why make this change?

• To implement continuous integration and delivery for the Rust project, ensuring code quality and automated testing
• To provide transparency about the project's build status through the CI/CD badge
• To showcase the performance advantages of nyx-ψ over TCP and UDP in lossy network conditions, demonstrating its effectiveness and potential use cases
