use pybind11 package in VSCODE

[gitouni]

Hello, @smrfeld ,Thanks for sharing this pybind11-cmake tutorial! Actually, This is not a issue but a request.

I am a beginner of pybind11 and this project helps me a lot. However, I am wondering how to let VSCODE automatically highlight pybind package like ordinary python pacakge, as well as automatically complete args and function names. Should I add py.in files?
