Allow Unquoted Strings with CR in CSV Format

Why it matters

This feature addresses the limitation where unquoted strings in CSV input could not contain carriage return characters. It improves CSV parsing robustness by enabling users to import CSV data that includes \r within unquoted fields without errors.

How to use it

Users can now import CSV data as usual without needing to quote strings that contain \r characters. No additional configuration is required to enable this behavior.
