Imp package is deprecated in Python 3.12

Hello,

I've just installed your package and I ran into a problem importing the library.

Seems that Imp has been deprecated as per the documentation. So if you create a new anaconda environment for instance you should be installing Python 3.11 to make the library work.

I believe this should be stated somewhere in the installation manual, until the code is upgraded to be compatible with Python 3.12

Thank you, I simply put an upper limit in the setup file. so that pip install should complain if python is >=3.12.
I Still need to upgrade the corresponding functions for >=3.12.
