Bilibili Video Subtitle Tracks (by aid and cid)

omnial/bilibili-video-subtitle-tracks

Given a Bilibili video's numeric aid and one part's cid, lists the subtitle tracks the part has: each track's ID, language code (an ai- prefix marks an AI-generated track), language name and locked flag, plus whether viewers may submit subtitles. It does not return the subtitle text or a link to it. One AI Chinese track in testing.
