Currently in our GCP downloader flow we send a single file to the `download_file` method at a time. The problem with this is when you have a large customer with multiple files to be processed! (multiple files for a single day)

when we call 'create_daily_archives' within the download method we overwrite previously create daily archives for each new download_file with additional SAME DAY daily data. What we really need to be doing is passing the full list of downloaded files to the 'create_daily_archives' method so we can process them all in iteration. NOT OVERWRITING THEM.
