Drop outdated engine attributes: supported_languages, language_aliases
Complete, normalize and document the type definitions for the engine-module and
engine-class.
For the ``engine.about`` section of the configuration, a type check is performed
based on structure ``searx.enginelib.EngineAbout``.
The property ``engine.about.language`` no longer exists; existing values have
been migrated to ``engine.language``.

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`.
