It’s not obvious that the function will fail in some cases and throw
an `IllegalArgumentException`.
So instead of just failing if parsing fails, return an Optional that
all callers have to decide what to do (e.g. the YoutubeExtractor can
just ignore the locale in that case, like it does with most other
fields in the json if they are unexpected).
- Handle special cases for languages where the number is not shown
- Rework the Downloader base implementation, allowing for more
advanced things to be done
- Separate the localization from the content country (just like
YouTube let's the user choose both).
