Initializes NATS for nalpaca. You'll need the NATS cli.
Editing any of the JSON files this script uses in $dir to fit your
needs can be okay if you are editing things that don't bother nalpaca.
Settings that should not be touched are the stream names and the subjects
  
Editing subjects is not supported and will break your installation
