Substack to EPUB Converter

This project is a Python script that converts a Substack newsletter archive into an EPUB file. The script fetches articles from a Substack publication, converts them into HTML chapters, and compiles them into an EPUB file. It uses the Substack API and requires a valid session cookie to retrieve content.

• Creates a fully formatted EPUB with metadata including author and newsletter name.
• Handles pagination to ensure all available articles are included.
