Run a command within the PlotM monad. Stderr stream is read
and decoded, while Stdout is ignored. Logging happens at the debug
level if the command succeeds, or at the error level if it does not
succeed.
Called before a command is about to run. The first argument is the
step index and the second is a string representing the command about
to be run.
