feat: Refactor formatting and extraction logic

- Added `langcodes` dependency for improved language handling.
- Replaced `ColorFormatter` with `TextFormatter` for consistent text styling across the application.
- Introduced `TrackFormatter` for better track information formatting.
- Updated `MediaFormatter` to utilize new formatting methods and improved data handling.
- Refactored `MediaExtractor` to enhance data extraction logic and improve readability.
- Removed deprecated `ColorFormatter` methods and replaced them with `TextFormatter` equivalents.
- Added new methods for extracting and formatting audio and subtitle tracks.
- Updated tests to reflect changes in the extraction logic and formatting.
