--formatter="lines" is not supported via the CLI

[morgan-zylotech]

The help message states that grouped and inline-grouped are the only available options, however the documentation in the README.md file implies that you can also use lines. I was only able to get lines to work properly when adding

{
  "formatter": "lines"
}

to an importanize.json file

I suppose you can either add lines as part of the CLI or update the README.md file to state that lines is not available via the CLI
