These exceptions are thrown on a test with the error messages text, because YouTube returns only "UNPLAYABLE" status in most error cases.
Tests are based with English strings, so changing the lang used by
extractor will throw the generic exception (ContentNotAvailableException).
This commit adds two new exceptions in NewPipe Extractor: GeographicRestrictionException and SoundCloudGoPlusException (which extend to ContentNotAvailableException). These exceptions allow showing different error messages to user when a content isn't available in his/her/its country (only used for now by SoundCloudStreamExtractor) or when the content is a SoundCloud Go+ track.
Sometimes YouTube introduces recaptchas only on some pages. By adding an url to the ReCaptchaException the NewPipe app is able to use that url to load the page that originally caused the problem.
Also removed every instance of exception caught and rethrown with a different description: it makes no sense and it removes part of the useful stacktrace.
