Is your feature request related to a problem? Please describe

Radarr now only recognizes three-letter language codes, such as eng. Unfortunately, all Czech trackers use two-letter codes such as EN. I can find out what languages a movie contains using regex. But I cann't verify if any of these languages are the original language. Since I'm downloading movies for myself and the rest of the family, who don't want to watch movies with subtitles, I need the movies to include both the original language and dubbing.

Describe the solution you'd like

Automatically recognize two-letter language codes at least the most commonly used languages by default. Alternatively, have the option to check this option in the settings.

Describe alternatives you've considered

I was thinking about the possibility of renaming the language codes in the movie title before analyzing it, or checking custom formats against the original language found from the TMDB.

Anything else?
