Feature: support --annotation-style line

[zetsumeishi]

Hello,

I wasn't able to find a related issue. Would it be possible to add this option. We would have annotation-style split for default behavior just as now but an option like --annotation-style-line would add the option.

I would be willing to do the PR if necessary.

Thank you :smile:

Hi @zetsumeishi, I'll be happy to review a PR. At high-level, you'll need to add a new module in features and wire it up in FeaturesController. Please make sure to add some tests that both annotation styles are supported by the parser.
