Adding a config file to replace CLI arguments

[abdul-alhasany]

Is your feature request related to a problem? Please describe.
Currently the package is working fine but the the CLI arguments might be too many to handle. I have a project that has many nested files and it is cumbersome to selectively add folders. Even when running as a npm script, this are is still an issue of maintenance (if folder structure changes .. etc)

Describe the solution you'd like
Having a JS config file would solve the mentioned issue and provide more capabilities (e.g. adding logic)

Describe alternatives you've considered
Using npm script.

Additional context
Thanks for this package and I hope that it is still maintained. I had a difficult time finding an actively maintained package that could document vue components (even styleguide did not work) until I found this one.
I would be happy to help with a PR if this is feature is considered.
