Bugfix/97 crashes when processing directory

[melane6]

The pull request adds support for processing entire directories of input files in ReX, The main changes enable users to specify a directory as input, which will trigger ReX to process all files within that directory. Additionally, there are updates to how output paths are handled when working with directories.

Directory processing support:

• Added a directory boolean attribute to the CausalArgs configuration, set automatically if the input path is a directory, allowing ReX to process all files in the directory (rex_xai/input/config.py, rex_xai/rex_wrapper.py).
• Updated the main entry point to iterate over all files in a directory when args.directory is set, running the explanation pipeline on each file (rex_xai/rex_wrapper.py).

Output path handling improvements:

• Modified output path logic in the explanation function to generate unique output file names when processing directories, preventing file overwrites (rex_xai/explanation/rex.py).

Minor Changes

• Reformatted code with ruff
