`mpi4py>=4.0` were released and support MPI 4 features. But Lassen does not support MPI 4 in the IBM Spectrum rolling releases. Thus, limit the upper versions of `mpi4py` for now. Also making the compilers for `h5py` a bit more robust, using the Lassen-specific wrapper name (hey, thanks for being special). https://hpc.llnl.gov/documentation/tutorials/using-lc-s-sierra-systems#Compilers
