[ ] 断点续传进度显示不准确
[ ] 断点续传应该检查下已经下载的文件和要下载的文件是不是同一个（尺寸大小，链接是否一致等等）
[ ] 下载过程记录耗时
[ ] 单任务失败后需要支持重试（分片下载时有可能出现错误“”导致整个任务结束）
[ ] m3u8 中的 ts 文件如果加密了要支持解密 https://juejin.cn/post/6887575078293372942#heading-0 https://github.com/Momo707577045/m3u8-downloader
需要指定 referer 才能生效的 m3u8 文件（内部已经默认注入） https://v9.xszav.net/hls/xszavavs/media/videos/h264/118886_SD.mp4/index.m3u8
重定向且加密的 m3u8 文件 http://video.yjf138.com/20180812/6yl0Q2YZ/index.m3u8 http://video.yjf138.com/20180812/6yl0Q2YZ/1500kb/hls/index.m3u8
