Photo-organizer

Changed

- Refactored the `main` function to improve code modularity and readability by extracting logical components into separate functions.

Added

- Unit tests for core functions using `pytest`.

Fixed

- Improved logging messages for better debugging and clarity during file operations.

Added

- New optional flag `--no-year` to place month folders top-level with the format `YEAR-MONTH` instead of inside a year folder.
- The `--no-year` option also supports daily folder structure, creating a `YEAR-MONTH/DAY` folder structure.

Added

- Initial release of Photo Organizer.
- Move photos from a source directory to a target directory organized by year and month.
- Support for recursive file search with the `-r`, `--recursive` flag.
- Option to organize photos into daily folders with the `-d`, `--daily` flag.
- Filter photos by file extensions with the `-e`, `--endings` flag.
