minor: when using --csv option, chart-review should still print summary info

[comorbidity]

For example, when not using the --csv flag we see the additional metadata

That would mean you couldn't pipe the output to a csv file.

We could try to detect a real tty vs a file output... Or we could print that content out to stderr, but that feels like a misuse of the error stream. But could be a way to get that behavior.

@mikix OK , I appreciate your point. This is minor point , and the workaround of not using --csv flag is trivial, so we can close this ticket if you like.
