Add the possibility to easily turn on bundle analyze

[ezhlobo]

I think we should build in webpack-bundle-analyzer and make it used for dreact app. For example dreact app build --analyze.

An alternative is officially recommended source-map-explorer: https://create-react-app.dev/docs/analyzing-the-bundle-size/

For running bundle analyzer I'd recommend turning off optimizaation#concatenateModules in the webpack config. It makes the research of what is going on inside the bundle easier.

One more tool for analyzing is https://statoscope.tech/ that helps you inspect stats.json from webpack
