    Copy files between FileSystems.

This functions allows you to recursively copy directories of files from
    one file system to another, such as from S3 to your local machine.

Parameters
    ----------
    source : string
        Source file path or URI to a single file or directory.
        If a directory, files will be copied recursively from this path.
    destination : string
        Destination file path or URI. If `source` is a file, `destination`
        is also interpreted as the destination file (not directory).
        Directories will be created as necessary.
    source_filesystem : FileSystem, optional
        Source filesystem, needs to be specified if `source` is not a URI,
        otherwise inferred.
    destination_filesystem : FileSystem, optional
        Destination filesystem, needs to be specified if `destination` is not
        a URI, otherwise inferred.
    chunk_size : int, default 1MB
        The maximum size of block to read before flushing to the
        destination file. A larger chunk_size will use more memory while
        copying but may help accommodate high latency FileSystems.
    use_threads : bool, default True
        Whether to use multiple threads to accelerate copying.

Examples
    --------
    Copy an S3 bucket's files to a local directory:

>>> copy_files("s3://your-bucket-name", "local-directory")

Using a FileSystem object:

>>> copy_files("your-bucket-name", "local-directory",
