let mut website = Website::new("https://example.com");
website.configuration.parallel_backends = Some(ParallelBackendsConfig {
    backends: vec![BackendEndpoint {
        engine: BackendEngine::LightPanda,
        endpoint: Some("ws://127.0.0.1:9222".to_string()),
        binary_path: None,
        protocol: None,
    }],
    ..Default::default()
});
website.crawl().await;
