Async wrapper for cloudflare/lol-html.

Since lol-html 2.x, [lol_html::HtmlRewriter] supports Send via the [lol_html::send] types. This crate wraps it in an [AsyncRead] implementation, feeding input from an inner async reader and producing rewritten HTML output.

use lol_async::html::{element, html_content::ContentType, send::Settings};

let mut reader = lol_async::rewrite(
    Cursor::new(r#"<html>
<head><title>hello lol</title></head>
<body><h1>hey there</h1></body>
</html>"#),
    Settings {
        element_content_handlers: vec![element!("h1", |el| {
            el.append("<span>this was inserted</span>", ContentType::Html);
            Ok(())
        })],
        ..Settings::new_send()
    }
);

let mut buf = String::new();
reader.read_to_string(&mut buf).await?;

assert_eq!(buf, r#"<html>
<head><title>hello lol</title></head>
<body><h1>hey there<span>this was inserted</span></h1></body>
</html>"#);
