Selecting npz writes wrongly nested data

[konstin]

Writing an .npz file creates a file that contains a dict with one entry arr_0 mapping to a zero-dimensional array that contains the dict with the actual data.

Likely this can be fixed by replacing np.savez(emb_path, emb_dict) with np.savez(emb_path, **emb_dict).

Fixed.
