##### SUMMARY
`get_url` inherits from `add_file_common_args`, which includes `unsafe_writes`, however our call to `atomic_move` does not pass this argument along.

      - 'If a checksum is passed to this parameter, the digest of the
        destination file will be calculated after it is downloaded to ensure
        its integrity and verify that the transfer completed successfully.
        Format: <algorithm>:<checksum|url>, e.g. checksum="sha256:D98291AC[...]B6DC7B97",
        checksum="sha256:http://example.com/path/sha256sum.txt"'
      - If you worry about portability, only the sha1 algorithm is available
        on all platforms and python versions.
      - The third party hashlib library can be installed for access to additional algorithms.
      - Additionally, if a checksum is passed to this parameter, and the file exist under
        the C(dest) location, the I(destination_checksum) would be calculated, and if
        checksum equals I(destination_checksum), the file download would be skipped
        (unless C(force) is true). If the checksum does not equal I(destination_checksum),
        the destination file is deleted.
