    Parse XET file metadata from an HTTP response.

    This function extracts XET file metadata from the HTTP headers or HTTP links
    of a given response object. If the required metadata is not found, it returns `None`.

    Args:
        response (`requests.Response`):
            The HTTP response object containing headers dict and links dict to extract the XET metadata from.
    Returns:
        `Optional[XetFileData]`:
            An instance of `XetFileData` containing the file hash and refresh route if the metadata
            is found. Returns `None` if the required metadata is missing.
