compatibility with Geant4 > 11.0

Hello. Thank you for your amazing work.
I tried to install the g4python with Geant4 11.1 and 11.2, and it seems that there are quite several changes in the version, like changes in G4persistence, G4tasking, and G4VTouchable.

I was wondering if you are planning to update the code for the newer version of Geant4.

Thank you!
