Add NIP-11 relay synchronization and group management features

- Introduced a new `sync` package for managing NIP-11 relay information and relay group configurations.
- Implemented a cache for NIP-11 documents, allowing retrieval of relay public keys and authoritative configurations.
- Enhanced the sync manager to update peer lists based on authoritative configurations from relay group events.
- Updated event handling to incorporate policy checks during event imports, ensuring compliance with relay rules.
- Refactored various components to utilize the new `sha256-simd` package for improved performance.
- Added comprehensive tests to validate the new synchronization and group management functionalities.
- Bumped version to v0.24.1 to reflect these changes.
