Would this also mean that we can remove this dependency from the Cargo.toml?

serde_repr = "0.1"

Thanks for your continual efforts to modernise the repo; is there a particular motivation behind this PR beyond just bringing norad more up-to-date?

No ... that's what makes it available for use. Just that since Rust 2018 edition, the extern crate is no longer needed, just having it in the Cargo.toml is enough.

Sadly, no! I just help out on a bunch of the linebender repos and this is in the linebender organization!

I don't even know what UFO files are (beyond what the readme says).

My bad, I completely missed the usages of serde_repr's macros in the source code, I thought it might have been an unused dependency

Thanks for your time!
