Adding callback_future_once on LinkFuture trait (yewtil crate)

[fraillt]

It would be nice to have callback_future_once, as it matches nicely with callback_once.
also it looks much cleaner.

self.link.callback_future_once(|_| async move {
    Msg::FileUploaded(upload_form.post_async().await)
})

vs.

self.link.callback_future(move |_| {
    let upload_form = upload_form.clone();
    async move { Msg::FileUploaded(upload_form.post_async().await) }
}),

Implementation is pretty simple as well.

impl<COMP: Component> LinkFuture for ComponentLink<COMP> {
...
    fn callback_future_once<FN, FU, IN, M>(&self, function: FN) -> yew::Callback<IN>
    where
        M: Into<Self::Message>,
        FU: Future<Output = M> + 'static,
        FN: FnOnce(IN) -> FU + 'static,
    {
        let link = self.clone();

        let closure = move |input: IN| {
            let future: FU = function(input);
            link.send_future(future);
        };

        Callback::once(closure)
    }
...
}

Does it needs more discussion, or maybe I can make a PR? :)
