fixes removed module in Python 3.12

[Spoffy]

The 'imp' module was removed in Python 3.12.

This replaces it with a generic named ModuleType, which has an identical dict property.

This is a strange question for 2024 but do you know if this works in Python 2.7? Our SaaS still has some early adopter users on 2.7

[Spoffy]

Good question @paulfitz! The type definitely exists in 2.7, but I'll check it runs as expected.

[Spoffy]

This works with Python 2.7, tested in our docker container with Python 3 removed.

Thanks @Spoffy !
