Python class inherit from PyO3 class

[jblindsay]

Is it possible for a Python defined class to inherit from a PyO3 class? I've tried this and I receive an error indicating that, builtins.WbEnvironment' is not an acceptable base type. Is there perhaps a flag in my PyO3 project that I need to use to indicate that the class WbEnvironment is not final?

You need to add #[pyclass(subclass)], c.f. https://pyo3.rs/v0.20.0/class#customizing-the-class

I figured it was something simple like that. Not sure how I missed that in the docs. Thanks for your help.
