Fetch dependencies in the given target

This script will fetch dependencies with all corresponding files(.whl,.tar.gz,.LICENCE,.NOTICE,.ABOUT) from the given target . This feature will ask  ScanCode's developer to provide dependencies as package_name,version and target directory where the built wheels and tarballs would be fetched.
