Octal literal is deserialized as decimal

[isegal]

When passing an octal number as per specification at https://yaml.org/refcard.html
The value does not get parsed as octal.

Ex:

#[test]
fn test_octal_deserialize() {
    let source = r#"
---
value: 0755
"#;
    #[derive(Serialize, Deserialize, PartialEq, Debug)]
    struct TestOctal {
        value: u32,
    }
    let result: TestOctal = serde_yaml::from_str(&source).unwrap();
    assert_eq!(result, TestOctal{
        value: 0o755
    });
}

Expected :TestOctal { value: 493 }
Actual :TestOctal { value: 755 }

That link describes yaml 1.1. This library implements yaml 1.2 which uses 0o prefix for octal.

value: 0o755

Just tested with 0o prefix. Works as expected. Thank you.
