[NextJS] Enhanced component scaffolding

[mjarosch]

Is your feature request related to a problem? Please describe.

Enhance the component scaffolding ability to allow for more customization, adding folder structure and generating additional files like storybooks or test

Describe the solution you'd like

As a JSS developer, when I am creating a new component, I would like to be able to run a command that generates the starting files (JSX, Tests, Storybooks, Mock Data, etc.) that our project commonly has in a component.

As a JSS developer, I should be able to configure this generation with settings and questions specific to my project.

Describe alternatives you've considered

The default scaffolding does not support these advanced items, like additional files. There is an opensource project that has some of these options, but they no longer support it.

Additional information

I am putting together thoughts for an implementation and would like community feedback as I work on an implementation and future pull request. It includes support for an enhancement request and will probably include additions to my theme PR.
