feat(parser): site category prefix, RSS embedded description and subtitle titles (ID-2)

Strip [电视剧]/[动漫]/[音乐]… prefixes into parsed.category instead of titleCn,
split RSS-embedded site descriptions into the subtitle, take the first Chinese
name of the subtitle as titleCn and the rest as altTitles, and stop reading
'Travis - 12 Memories' as episode 12. PARSER_VERSION 2.
