Boolean fields specified with integers always parse as true

[csssuf]

Boolean fields specified as integers always seem to parse as true, even with contents of 0:

#[macro_use] extern crate serde_derive;
extern crate serde_xml_rs;

#[derive(Debug, Deserialize)]
struct Structure {
    boolean_field: bool,
}

fn main() {
    let s = r##"
        <Structure boolean_field="0">
        </Structure>
    "##;
    let test: Structure = serde_xml_rs::from_reader(s.as_bytes()).unwrap();
    println!("{:#?}", test);
}

This test program outputs:

Structure {
    boolean_field: true
}

This seems to be a duplicate of #18, please see my reasoning there.

Note that you can always use #[serde(deserialize_with=foo)] to overwrite the behaviour to match your use case. (See https://serde.rs/field-attrs.html for details on how to do that)
