Python script that will call conan twice (Debug and Release) and generate a premake5 lua file to use both configuration simultaniously

conan.py

"""
Simple python script for using conan Debug and Release configurations 
simultaniously. Take the normal (non generator) create conanbuildinfo.txt
and converts it to a proper premake5 lua file. Invokes conan twice with
build_type=Debug and build_type=Release

!IMPORTANT!
This Script is not compatible with conan >= 2.0.0
If you are looking for a conan >= 2.0.0 solution for premake5, consider

Revision: 3 (10.03.2023)

Revisions:
1) - Initial draft
2) - Added support for emitting lua strings that contain quotation marks 
   - The tool now outputs all variables/output from conan as lua arrays
3) - Fixed more lua invalid chars (both in vars and strings)
