…fmp4，回退至ts，支持直播备份地址，目前的小问题，画质选项中会出现HLS相关选项，貌似是potplayer特性。

Pull request overview
该 PR 针对 Bilibili 直播播放解析切换到新版直播播放接口（getRoomPlayInfo），以适配更多编码/封装与备份地址输出，从而提升直播播放的兼容性与可选项。
Changes:
- 新增直播画质映射（
getLiveQuality），并在直播解析中基于新版playurl_info解析协议/封装/编码信息。 - 直播流优先选择
fmp4，无fmp4时回退到ts，并为主地址提供备份地址条目。 - 直播画质列表按 codec（AVC/HEVC/AV1）分别生成对应 URL 与 itag。

- 备份流的 itag 同样建议使用 getLiveItag(qn)，保持与主流一致的排序/选择逻辑。
qualityItemBackup["itag"] = getItag(temp_codec["current_qn"].asInt()) * 100 + codecOffset * 10 + 1;
