Current Behaviour

The following test fails with

'called `Result::unwrap()` on an `Err` value: Custom("invalid type: integer `42`, expected unit")'

#[test]
fn serde_other_value() {
    #[derive(Deserialize)]
    enum E {
        A(u32),
        #[serde(other)]
        Unknown,
    }

    #[derive(Serialize)]
    enum F {
        A(u32),
        B(u64),
        #[serde(other)]
        Unknown,
    }

    let mut buf = vec![];
    let b = F::B(42);
    ciborium::ser::into_writer(&b, Cursor::new(&mut buf)).unwrap();
    let unk_from_reader: E = ciborium::de::from_reader(Cursor::new(&buf)).unwrap();
    // It works when deserializing directly from the reader
    assert!(matches!(unk_from_reader, E::Unknown));

    let v: ciborium::Value = ciborium::de::from_reader(Cursor::new(&buf)).unwrap();
    let unk_from_value: E = v.deserialized().unwrap();
    // This is the failing assertion
    assert!(matches!(unk_from_value, E::Unknown));
}

Expected Behaviour

I expect the Unknown variant to be deserialized regardless of whether there's an intermediate Value step.
