extension WebPDecoder: ImageDecoder {
    public func decode(data: Data, response: HTTPURLResponse, options: ImageDecodeOptions?) throws -> Image {
        let contentTypes = response.allHeaderFields.filter({ ($0.key as? String ?? "").lowercased() == "content-type" })
        guard
            let contentType = contentTypes.first,
            let value = contentType.value as? String,
            value == "image/webp",
            let image = WebPDecoder.decode(data) else {
                return try DefaultImageDecoder().decode(data: data, response: response, options: options)
        }
        return image
    }
}

// Set decoder to shared ImageDownloader
Vulcan.defaultImageDownloader.decoder = WebPDecoder()

// Request image with URL
imageView.vl.setImage(url: URL(string: "/path/to/image")!)
