When `x` is an `Enum`, duper `get_reduce` raises an error about duper

Hi, thanks for report and in-depth description!

Sorry for a long answer, took a pause from GitHub :)

I see the issue you're describing, but can't come up with a use case that would reproduce it.

Please, provide end-to-end example of how you're using duper and the stack trace you're getting.

PR is also welcomed, once issue is confirmed!

Took a quick look at this issue, this one may be a bit challenging especially due to the enum changes over the last few Python minor versions. Enum class does a couple of gnarly things under the hood to get it working.

In most scenarios, I can't imagine why you'd need a duplicate Enum class? Isn't the whole point to represent static data?
