Bug: U+2028 not escaped in strings

[ghost]

Description

• Contrary to recommendations of the spec, the Unicode code points U+2028 and U+2029 are not escaped upon serialization. See Section 5.2 of the specification.
• Deserialization fails when an input string contains Unicode code points U+2028 or U+2029.

Tested Versions

json5 = "0.2.7"
serde = { version = "1.0.106", features = ["derive"] }

Testcase

#[cfg(test)]
mod tests {
    use serde::{Serialize, Deserialize};
    use json5;

    #[derive(Clone, Debug, PartialEq, Eq, Serialize, Deserialize)]
    struct S {
        value: String
    }

    #[test]
    fn roundtrip_u2028() {
        let original = S {
            value: "\u{2028}".to_string()
        };

        let serialized = json5::to_string(&original).unwrap();
        let deserialized = json5::from_str::<S>(&serialized).unwrap();

        assert_eq!(deserialized, original);
    }
}

Any update on this one still failing? I just got bitten with parsing a remote JSON file which includes "\u{2028}". I've fixed it by replacing it before passing it to json5.
