feat(sqltypes): add nullable SQL types with automatic casting

* Introduced SqlNull type for nullable values with auto-casting.
* Implemented JSON, YAML, and XML marshaling/unmarshaling.
* Added specific types for common SQL types (e.g., SqlInt64, SqlString).
* Included utility functions for creating nullable types.
* Added SqlTimeStamp, SqlDate, and SqlTime types with custom formatting.
