        """
        Post an image, video or audio file. `media_file` can either be data or
        a file name. If data is passed directly, the mime type has to be specified
        manually, otherwise, it is determined from the file name. `focus` should be a tuple
        of floats between -1 and 1, giving the x and y coordinates of the images
        focus point for cropping (with the origin being the images center).

        Throws a `MastodonIllegalArgumentError` if the mime type of the
        passed data or file can not be determined properly.

        `file_name` can be specified to upload a file with the given name,
        which is ignored by Mastodon, but some other Fediverse server software
        will display it. If no name is specified, a random name will be generated.
        The filename of a file specified in media_file will be ignored.

        Starting with Mastodon 3.2.0, `thumbnail` can be specified in the same way as `media_file`
        to upload a custom thumbnail image for audio and video files.

        Returns a :ref:`media dict <media dict>`. This contains the id that can be used in
        status_post to attach the media file to a toot.

        When using the v2 API (post Mastodon version 3.1.4), the `url` in the
        returned dict will be `null`, since attachments are processed
        asynchronously. You can fetch an updated dict using `media`. Pass
        "synchronous" to emulate the old behaviour. Not recommended, inefficient
        and deprecated, will eat your API quota, you know the deal.
