H5py installation issue

[fankiat]

The h5py package recently released a new version, which uses an old version of mpi4py that has a typo. The fixed mpi4py is not referenced in the latest version of h5py, although they have already patched the issue but have yet to release the updated version. Hence, as a workaround until h5py release the fixed version, one can install sopht-mpi by adding the following lines in the Makefile to install h5py with MPI support.

pip install wheel cython
HDF5_MPI="ON" CC=mpicc pip install --no-build-isolation --no-binary=h5py h5py

This approach is also used in other projects as a workaround (see h5py/h5py#2222). Since this is not a sopht-mpi issue, we won't be fixing it, but will instead wait for the latest h5py version release.

This issue is temporarily fixed in #186 . I will leave this issue open until h5py release the new version, beyond which we will then remove the temporary fix and close this issue.
