jiter does not compile with the python feature

[decorator-factory]

My Cargo.toml:

[package]
name = "scratch"
version = "0.1.0"
edition = "2021"

[dependencies]
jiter = { version = "0.5.0", features = ["python"] }

I get an error after running cargo build:

What am I doing wrong?

System information:

• rustc 1.80.0
• Ubuntu 22.04

It definitely does in tests.

Cc @davidhewitt, any pointers?

I think #126 should fix this.

Thanks for looking into this 👍
this seems to work for me as a workaround

[dependencies]
jiter = { version = "0.5.0", features = ["python"]}
pyo3 = { version = "0.22.2", features = ["num-bigint"]}
