Rename Enum Variants

[yodaldevoid]

Is there currently any way to expose a different name for an enum variant to python from the one used in Rust? I like to use names that fit the standard Python formatting from my Python API, but this means that I either need to have enum variants that don't match the Rust formatting throughout my Rust code, or I need to duplicate each enum to have Rust version and a Python version.

I would accept a PR to add #[pyo3(name = "...")] support for enum variants!

Fair enough #2457
