- Added new dependencies: `colored`, `lazy_static`, `sqlformat`, and `unicode_categories` to improve code readability and SQL formatting capabilities.
- Introduced a new module `format_sql` for better SQL query formatting in `fit_model.rs`.
- Updated `fit_model.rs` to utilize the new `format_sql` function for logging SQL commands, enhancing clarity in database operations.
- Adjusted the `Cargo.toml` and `Cargo.lock` files to reflect the new dependencies and their versions.
These changes improve the maintainability and readability of the code, particularly in the context of SQL operations.
