Enhance download.py with Parallel Download Capability

[abilzerian]

This pull request introduces a significant improvement to the download.py script by implementing parallel downloads using ThreadPoolExecutor. This enhancement is designed to speed up the process of downloading files from the specified source.

Key Changes:

• Integrated ThreadPoolExecutor from concurrent.futures for parallel file downloads.
• Added error handling for HTTP errors and JSON decoding, improving the script's robustness in various network conditions.
• Maintained the original script's functionality, ensuring compatibility with existing usage patterns.

Benefits:

• Increased Efficiency: By downloading multiple files simultaneously, the overall completion time is significantly reduced, especially beneficial when dealing with large numbers of files.
• Improved Error Handling: The script now gracefully handles potential errors, providing clear messages for troubleshooting.
• Scalability: The number of workers for ThreadPoolExecutor can be adjusted, allowing users to optimize performance based on their specific environment and network conditions.

This update aims to enhance user experience by reducing waiting times and improving the reliability of the download process. It's particularly useful for bulk downloading tasks in environments with robust network infrastructure.

I think you have a problem with the edge case of a thread that already downloaded a file
