Bug: Empty Row Deletion Fails

The delete_rows method fails when attempting to delete empty rows (rows with no data), returning the error "Row number '{r}' is not valid." This occurs because the method incorrectly validates row existence by checking for cell data in worksheet.sheet_data, which is absent for empty rows. This prevents users from deleting empty rows or ranges that include them. The method should allow deletion of any valid row index, treating empty rows as valid and collecting an empty HashMap for their old_data in the diff.

	None => return Err(format!("Row number '{r}' is not valid.")),
