Implement these changes to this script:
• Add a progress bar.
• Add logging capabilities to log the script's activities, errors, and paths that were processed.
• Use concurrent processing to handle large directories more efficiently by calculating sizes in parallel.
• Use a configuration file to allow the user to choose whether the output is saved to a text file, CSV or JSON file in addition to printing it to the console.
• Improve error handling for various scenarios such as inaccessible paths, permission issues, or broken symbolic links.
• Allow users to set a size threshold using a configuration file to filter and display only items above or below a certain size.
• Provide additional summary statistics like average file size, number of files, number of folders, etc.
