- 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.
