ImGui LuaJIT FFI wrapper Generator

This is a python3 script that generates LuaJIT FFI bindings and lua wrappers by parsing the imgui header file via clang.

Used in BeamNG to generate the ImGui wrapper

   • on Ubuntu 20.04:

     apt install python3-pip clang libclang-dev libclang-6.0-dev
     pip3 install clang

   • on Windows 10: ensure python3 and pip are installed and usable from command line

     pip3 install clang

     install LLVM to the default install path, using a prebuilt *win64.exe installer from: https://github.com/llvm/llvm-project/releases
