slurm srun usage

[dnarayanan]

I'd like to edit scripts/hyperion to include something like:

if os.getenv("SLURM_SUBMIT_HOST") is None:
     mpi_command = "mpiexec"                   # SLURM?  No.
  else:
     mpi_command = "srun --mpi=pmix"           # SLURM?  Yes.

so that if the scheduling environment is SLURM, MPI will be run with srun instead of mpirun which is preferred (and, at least in our clusters case, required). I forked hyperion to do this and create a PR, but I can't figure out how to edit the code that goes to conda -- so more than an issue, this is a question as to how I can do that!
