Improve lab component export

[rosudhi]

Issue

Currently all exported method are in single location, but we may want those to be grouped based on it's component.

How to Reproduce

• import a component from @dhi/react-components-lab and we will see messed up component and it's belonging.
  

Expected

• Importing component from this @dhi/react-components-lab should return main component only, other supported type, method, etc should accessed from it's parent, @dhi/react-components-lab/{component_name}
