Bump version to 0.0.5 and update documentation

- Updated version in Cargo.toml and Cargo.lock to 0.0.5.
- Enhanced README.md to reflect the new version.
- Added `points_order` function to compute the orientation of three points.
- Included comprehensive tests for `points_order` covering various cases.
- Cleaned up whitespace and formatting in arc.rs and point.rs for consistency.
