Title: BF: fix invalid call to parent in minc classes

It was possible to call `data_from_fileobj` and `data_to_fileobj` from a
generic Header object, and the MINC classes use that object, so these could
cause confusion by making invalid calls. Raise NotImplementedError to reduce
potential confusion.
