The code was refactored and is now ES6 module based only. You can find the loader and related files here:
https://github.com/mrdoob/three.js/blob/dev/examples/jsm/loaders/OBJLoader2.js
https://github.com/mrdoob/three.js/tree/master/examples/jsm/loaders/obj2
Notice that LoaderSupport has been removed. It's best to study the related OBJLoader2 examples to understand the changes.
