CI fails for the Cargo.lock version=4 on ubuntu / 1.65.0. I'm not sure if and how this should be handled.

Thanks! Please do note #302 though, so may not get a release from this imminently

Easiest way to fix the 1.65 thing is simply to manually edit Cargo.lock (did that just now)

Ah, but the newer openssl requires Rust 1.70 😅 I guess time to bump it.
