Convert existing node trees to Geometry Script

Hi mate!

I don't suppose you've got functionality for going the other direction, converting nodes to code? This would save me a lot of time for not having to rebuild all of the node trees in code form manually.

I've created and maintain a project that relies on a bunch of pre-built geometry nodes groups (https://github.com/BradyAJohnston/MolecularNodes) which I am looking to convert to actual code (geometry-script) so that it can be version-controlled better than the currently opaque `.blend` file that they live in.

Any advice? cheers for the great project, which I will definitely be utilising in the future!
