Add class_path to allow generated components to reside in subdirectories

[matt-potter]

Summary

Although the documentation references rendering components from sub-directories, the generator only allows generation of components in the components/ directory. This PR adds class_path into the generated path, allowing use such as:

➜ rails g react:component frontend/my_component
Running via Spring preloader in process 45812
      create  app/javascript/components/frontend/MyComponent.js

Good idea @matt-potter , thanks for the contribution!
It looks good. I'll take a look into why the tests are failing, seems to be capybara suddenly upset in a totally different section of code.

Could you look into adding(or modifying) one test around this area for the new functionality please?

sure, will do! yep, didn't think the CI was anything related.

Hi @BookOfGreg, I've added a test and updated the readme

[BookOfGreg]

Lovely, that looks good. I'll fixup whatever is going on with CI and get it shipped. Hopefully within the week if I get time at work.

Great, thanks @BookOfGreg !

Looks like it was a combo of chromedriver + general ruby updates making master broken but that's close to fixed now.

Thanks again for contributing, hope you stop by to help again 😁
