根据不同的浏览器 UserAgent，服务器发送支持的格式。
\n另外 AVIF 虽然压缩率比较高，浏览器广泛支持，但也存在一些问题：
\n
\n
压缩/转码成 avif 较慢。
\n
不支持 progrssive decoding，导致没法在网络较慢时像 jpg 一样一行一行地加载，只能全部下载后才能加载。
\n比较理想的是 jpeg-xl，支持 progressive decoding, encoding 较快。

考虑到 Firefox 157 版将默认支持 JXL，murmur 未雨绸缪，提前支持 JXL 格式，根据 Accept header 自动发送合适的格式，拓展名不变，还是.avif。

经浏览器模拟 throttle，JXL 的渐进加载跟 JPG 的一行一行加载不一样，而是从上到下，从左到右的网格形式的渐进加载。同时 AVIF 等其他图片格式继续保留加载时的占位符，防止图片加载后文本位置发生变化。

目前服务器响应的图片格式顺序：JXL ~> AVIF > WEBP > JPG/PNG/GIF
