Set directory for process #63

Right now, if you want to start a process in a directory other than R's current dir, you need to call setwd() before starting the process, and then call it again afterward. And for extra safety, you would want to call setwd() in an on.exit, in case there's an error.

  old_dir <- setwd(new_dir)
  # In case we have an error in process$new(), use on.exit
  p <- process$new("ls", stdout = "|")$wait()

It would be nice if there were an option to process$new that let you set the working directory.

You can also use withr::with_dir. But yeah, we can have an option.
