There was a problem hiding this comment.
I think these switch cases can be easily rewritten by return std::to_string(std::get<typename LiteralTraits<type_id>::ValueType>(value_)); once #185 is merged.

- Implements the complete type casting logic for `iceberg::Literal` in the `LiteralCaster` class to align with the Java reference implementation. This is critical for expression evaluation and predicate pushdown. - Add basic implementation for fixed type. - Updated `ToString()` to match Java's output format for better consistency (e.g., `X'...'` for binary). - Added comprehensive unit tests to validate all new casting logic and `ToString()` formatting.
