Refactor for additional socktop connector library

- socktop connector allows you to communicate with socktop agent directly from you code without needing to implement the agent API directly.
- will also be used for non tui implementation of "socktop collector" in the future.
- moved to rust 2024 to take advantage of some new features that helped with refactor.
- fixed everything that exploded with update.
- added rust docs for lib.
