add JSON file into renderer??

[GillianYue]

I had trouble incorporating the Monkey.JSON file into the test class. In the current test class, the mesh is rendered as a cube, with the cube geometry in the react-three-renderer API.

          <mesh  rotation={this.state.cubeRotation}>
                <boxGeometry
                    width={1}
                    height={1}
                    depth={1}
                />
                <meshBasicMaterial
                    color={0x00ff00}
                />

            </mesh>

The examples I see online uses THREE.JSONloader to load the file, but when I tried to put that in I got a ton of errors... Need more research on this
