Alternative to React and React Reconciler

[malash]

Since GojiJS is a React-based framework the react and react-reconciler became necessary dependencies that cost about 80kb of the main package size.

As we knew, there are several alternatives to React and React DOM from the opensource community, and some of them, for example, the Preact, can provide the almost same features within as less as 3kb.

This issue proposes to create a new package @goji/react to replace the React and React Reconciler while keeping the API compatibility.
