Module file_handler 

File handling module for sqawk

This module provides a unified interface for loading and saving different file formats:

• CSV files (comma-separated values)
• Delimiter-separated files (tab, colon, etc.)

It abstracts away the specific file format details and provides a consistent API for the rest of the application to work with in-memory tables.
