I created a wrapper for better overload handling

[marwndev]

I have created this wrapper to better handle overloads. You can check the details here:
https://www.npmjs.com/package/occjs-wrapper

It is built by reading the typescript type definitions in opencascade.full.ds.ts and generate the appropriate classes.

I think it is possible to integrate this in the build process here. If anyone is interested in doing so please let me know.
