imp no longer exists in 3.12

[clausing]

Description Import from imp fail since imp is no longer supported in python 3.12. Generates lots of the the following error(s)

Traceback (most recent call last):

I believe this is caused by the maclookup package, which looks like it hasn't been updated since 2018(!) and doesn't work well with Python 3.12. I'll look at finding a different way to provide this functionality.
