"""Compute the score of the `subtitle` against the `video` with `hearing_impaired` preference.
patch:
- remove upper bounds of score
- re-add matches argument and remove get_matches from here
:func:`compute_score` uses the :meth:`Subtitle.get_matches <subliminal.subtitle.Subtitle.get_matches>` method and
applies the scores (either from :data:`episode_scores` or :data:`movie_scores`) after some processing.
