dataset dtype is not a numpy dtype

[bnlawrence]

I believe the HDF5 Dataset dtype is a numpy dtype (and hence has attributes like itemsize).

The easiest fix to this would be to return a numpy dtype in the Dataset property, but this would also require a change to the test_repr. Happy to make a pull request on this if desired.

I'd follow the README and consider that a bug which should be fixed.

(This has been hoovered up in the h5netcdf support to be incoming in the next couple of weeks.)

Confirming this as a bug. h5py returns a NumPy dtype object for the dtype attribute of a dataset, pyfive should as well.
