Hello Lucupy developers

First of all, thank you for using Gelidum. I did that library with the intent of helping the community and is good to see somebody sees useful.

The thing is that I just found that you are having some issues with the freezing of objects with __slots__.

I have a branch that (tentatively) supports freezing objects with __slots__. Can you confirm if it works for you? I could create a new release this week with that feature if it works fine.

Thanks a lot!
