Newline missing in generated batch script
**Bug description / feature request:**
When running struphy with `-b` but not with likwid. The `batch_script.sh` is incorrectly generated.
* Newline missing between "# Run command added by Struphy" and "srun ..."
* The srun command is now run with `srun -n str(mpi)` which means struphy will be run with the number of cores that are speciefied by `--mpi X` and NOT by the number of cores that are specified in the batch script. This is not how it was set up previously.
* Which method is preferred?
**Expected behavior:**
There should be a newline...
**Proposed solution:**
I will add an `\n` in console/run.py
