feat: Add script for cleaning and installing all dependencies

[denisogolubev]

This script does automatically all work you have to do manually in case you need to reinstall all dependencies from scratch: Steps:

• remove autogenerated directories (.angular, node_modules, lib, dist, documentation, storybook-static)
• remove autogenerated files (package-lock.json, documentation.json)
• remove all node_modules in ./packages
• remove all node_modules in ./packages/components
• remove all node_modules in ./src/app/ext
• run npm i

So, in case you need to reinstall dependencies, just run this script and go have a tea :) How to run the script you can find in top of the script file.
