Add datalink-provider crate for real-world AIS data handling
- Introduced a new crate, `datalink-provider`, to support real AIS data sources (serial, TCP/UDP, file replay). - Integrated it into the workspace and used it in the `AIS` system, replacing the simulation datalink. - Updated dependencies and lock file.
