BSB Neuron tutorial does not work without bsb-core[parallel]

[drodarie]

How to reproduce

Run the neuron-simulation example, but change its dependencies in the toml file so that it does not use bsb-neuron[parallel] but bsb-neuron instead.

Then, run the reconstruction and simulation:

bsb compile configs/guide_neuron.json -v 3 --clear
bsb simulate my_network.hdf5 neuronsim -o simulation-results

During the simulation, the following segmentation fault is raised:

numprocs=1

Even though the simulation was not run in parallel, it seems to require MPI libs to be present...
