Combine Text Files Script

This script combines all text files in a specified directory and writes their contents to a single text file,
with an option to also create a PDF file.

How to use:
1. Ensure you have the `reportlab` library installed. If not, install it with the following command:
    pip install reportlab

2. Save this script to a file, for example, `combine_text_files.py`.

3. Open a terminal and navigate to the directory where the script is saved.

4. Run the script with the following command:
    python combine_text_files.py /path/to/input/directory --output_text.txt --output_pdf output_pdf.pdf

   Replace `/path/to/input/directory`, `output_text.txt`, and `output_pdf.pdf` with the desired input directory and output filenames.
   If you don't want to create a PDF file, simply omit the `--output_pdf` option.
   e.g. python3 combine_text_files.py . --output_pdf output_pdf.pdf
