Hot Reload: Explore Experimental React Refresh Feature

[ryanelian]

react-hot-loader is deprecated soon, to be replaced with react-refresh. instapack should be ready to implement react-refresh when it's stable.

It'll be actually cool if instapack can do Fast Refresh React projects out of the box.

Should probably detect if React is installed in project package.json. If exists and Hot Reload server is on, then attach the webpack plugin and another JS/TSX loader specially for Babel early in the rule chain (executed last).
