Downloads the given instance of this dataset from dataset store.

        Parameters
        ----------
        version: str, optional
            The version of the instance of this dataset.
        tags : list of str, optional
            The tags associated with the given instance of this dataset.
        ext : str, optional
            The file extension to use. If not given, the default extension is
            used.
        overwrite : bool, default False
            If set to True, the given instance of the dataset is downloaded
            from dataset store even if it exists in the local data directory.
            Otherwise, if a matching dataset is found localy, download is
            skipped.
        verbose : bool, default False
            If set to True, informative messages are printed.
        **kwargs : extra keyword arguments
            Extra keyword arguments are forwarded to
            azure.storage.blob.BlockBlobService.get_blob_to_path.
