Update React version

[NBK-01]

The react version used in this version is 16.0.0, It would be useful to update the current react package to keep up to date with other technologies used in the same project.

Is the project still working for you? Apparently, Spline updated their runtime using module splitting making it really hard to use in this project.

Hey, Is this the reason it won't work in my react-app? I noticed in the documentation example, that it's looking for a spline.json file, but I'm just referencing the .spline file instead because there is no JSON file that comes with spline exporting.

I haven't tried using Spline with React, will update you if I try it out.
