[X3D-Ecosystem] Replace Nashorn with GraalJS on web3d.org

[John Carlson]

Oh, and pull requests for updating the 2 files to V4.1 welcome!

Note that there’s a headless version of X_ITE as well, so there’s no need
for another node-based JavaScript API, there’s one based on X3DJSAIL (my
generated one) and then Holger’s.

But yeah, I’m developing a web-based viewer for X3D JSON, React and
THREE.js.  It’s probably getting close to the VRMLLoader and
three-x3d-loader in capability, and even supports at least some animation.
I’m currently looking into font URLs.  But SAI is currently non-existent.
While I have a MVP, I don’t really know if it’s close to Interchange
profile yet.

If you’re interested in particular .x3dj files working in the viewer, send
them my way!  I feel this API will be more secure than a Schema.
