GISTDA sphere map component for ReactJS + demo

Modified from longdo-map-demo-reactjs

Replace mapKey value in ./src/map/Map.jsx with your own API key (get one here).
```
const mapKey = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
```
Import map component (Map) and instance (map).
```
import { map, Map } from "./map";
```

Call <Map /> and you should see the map, for example:

import React from "react";

import { map, Map } from "./map";

const App = () => {
  return (
    <div style={{ height: "80vh" }}>
      <Map />
    </div>
  );
};

Use map instance to use sphere API, for example:

map.goTo({ center: { lon: 100.510847, lat: 13.743757 }, zoom: 14 });
