Windows Path `\` gets lost after parsing

I have written the following test, that reproduces the issue: ```rust #[test] fn reproduce_backslash_error_from_string() { // GIVEN let expected_value = r#"C:\Users"#; let ini_string = format!("path={}", expected_value); // WHEN let ini = Ini::load_from_str(&ini_string).unwrap(); // THEN assert_eq!(ini.general_section().get("path").unwrap(), expected_value); } ``` This fails with: ```text assertion `left == right` failed left: "C:Users" right: "C:\\Users" ``` So I have this ini: ```ini path=C:\Users ``` And after parsing it becomes: ```ini path=C:Users ```
