Support Write on Virtual Dataset

See original GitHub issue

Hi! I’m currently working on a project that involves a possible write on HDF5 virtual dataset, specifically writing on the VDS will also write to the files that constructed the VDS. I tried the following but doesn’t seem to work:

f = h5py.File("test.h5", 'w')
f["vds"][4][3][2][1] = 1

Suppose the ‘test.h5’ already have a 4d VDS called “vds” , this assigment did not modify the VDS itself, left alone the files behind it. To be honest, I didn’t look into the C version of HDF5 API, but from the documentation, it seems that they support this functionality (not too sure) I wonder if h5py does support this feature that I missed some info from the documentation or it’s not supported at all.

@tacaswell I agree. I could take a closer look at the HDF5 library and follow up on the discussion
