- This gives users of this command a `--csv` option to pass to... you guessed
it, generate a CSV that's `pbcopy`able elsewhere, for more granular
breakdowns of where a person contributed.
- Inspiration was taken from the mockup in
https://github.com/Homebrew/brew/issues/13642#issuecomment-1254535251
but without the extra dependency of the TerminalTable gem.
- Always print a condensed "total contributions" sentence.
Output:
```
$ brew contributions issyl0
The user issyl0 has made 1201 contributions in all time.
$ brew contributions issyl0 --csv
