[fix] iqiyi: Add support for multiple videos per album

Add support for albums containing multiple videos in iqiyi engine. When
albumInfo contains a "videos" list, process each video individually to
create separate search results for each episode/video instead of a single
result for the entire album.

Also get video length from `duration` instead of `subscriptContent`.
