• Refactored out all conf side effects to functions and consolidated running context into a class.
• Instead of using the archive file name from the URL, we build a sha256 hash to use as an unique identifier
• We create folders using this hash, under download and extract folders, which makes it easier to look for the binary file.
• This refactor simplified downloader code as well.
