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)
}
