Cannot access compound dataset which contains array of enum about h5pyd

Hi, it looks like the test coverage for enum types is pretty thin - we'll want to beef this up.

I'm a bit confused just using h5py with your HDF5 file.
If I do this:

f = h5py.File("test.h5", 'r')
dset = f['test']
print(dset.dtype)
dt = dset.dtype["my_enum_array"]
print("enum dt: {}".format(dt))
print(h5py.check_dtype(enum=dt))

I'm getting "None" for the last output line. Is this what you see?

Yes, it seems that the metadata is lost if we access it that way. However, if I write f['test']['my_enum_array'].dtype.metadata (or equivalently, h5py.check_dtype(enum=f['test']['my_enum_array'].dtype)), the enum dictionary is retrieved as expected. This is pretty confusing behavior indeed.
