I don't think that anything that is in there already could do that.
However, maybe we can get away without a subclass. You'd only have to
get a string representation of the header and the image data, turn them
into an array and a dict and feed that to the constructor. So it could
simply be another helper function that could be linked into __init__().

What do you think?

Needless to mention that I'd be happy to accept patches and merge that
feature in pynifti.

Cheers,

Michael
