feat(format): Overhauled Langauge System

- Base language custom formats added, compiler will convert to other languages on the fly
- Not <Language>: Matches releases that don't include the specified language
- Not Only <Langauge>: Matches releases that include both the specified language, and others via parsed language logic
- Not Only <Langauge> (Missing): Matches releases that include both the specified language, and others via regex pattern "Dual Audio"
- New regex pattern to match dual audio
- Set default language to "Must Include English"
