Hello!
Just wanna start by saying I love the crate. I would like to improve the support for the structs in this crate by implementing FromWasmAbi and friends for structs in this crate, converting them to js_sys::Date. Maybe I could also implement support for converting structs in this crate to Temporal API objects behind some unstable feature flag and/or compilation options. This would enable users to do things like:

use wasm_bindgen::prelude::*;
use time::UtcDateTime;

#[wasm_bindgen]
struct MyStruct {
    pub time: UtcDateTime
}

I'd be happy to submit a PR with these changes if it sounds good!
