Add dependency license summary

[nandi95]

This would allow for better scanning of the licenses in the package and making a decision whether the user's product should use upfront or not. Devise a way to update the readme with a summary of the dependency licenses.

This could be an action that updates the readme when the package-lock.json file changes. It would create a commit? Or perhaps a third party service? https://github.com/davglass/license-checker https://github.com/RSeidelsohn/license-checker-rseidelsohn
