h5py and -disable-mpiio

[sigbjobo]

The option for --disable-mpiio seems not to work.

Managed to get it working installing parallel h5py by:
conda install -c conda-forge "h5py>=2.9=mpi*"
Which might be good to put in the guide!

Error with --disable-mpiio

Yes, this has to be fixed. We already have two open issues about it, #20 and #90.

This h5py API is incredibly unstable, they keep releasing backward-compatible breaking changes randomly in minor version bumps 😤

Sorry for the issue necromancy, but this works now as far as I can tell.
