feat: restructure renamer package and implement media extraction features

- Updated `pyproject.toml` to reflect new package structure.
- Created `renamer/__init__.py` to initialize the package.
- Implemented `RenamerApp` in `renamer/app.py` for the main application interface.
- Added constants for video extensions in `renamer/constants.py`.
- Developed `MediaExtractor` class in `renamer/extractor.py` for extracting metadata from media files.
- Created various extractor classes in `renamer/extractors/` for handling filename, metadata, and media info extraction.
- Added formatting classes in `renamer/formatters/` for displaying media information and proposed filenames.
- Implemented utility functions in `renamer/utils.py` for detecting file types and extracting media track information.
- Introduced `OpenScreen` in `renamer/screens.py` for user input of directory paths.
- Enhanced error handling and user feedback throughout the application.
