Init with literal

#[derive(Constructor, PartialEq, Debug)]
struct Example {
    #[init(10)]
    field: i32,
}

assert_eq!(Example::new(), Example {field: 10});

Call new func

#[derive(Constructor, PartialEq, Debug)]
struct Example {
    #[new("string")]
    field: Arc<String>,
}

assert_eq!(Example::new(), Example {field: Arc::new("string".into())});
#[derive(Constructor, PartialEq, Debug)]
struct Example {
    #[new(arc_string: String)]
    field: Arc<String>,
}

assert_eq!(Example::new("string".to_string()), Example {field: Arc::new("string".into())});
