#[cfg(feature = "std")]
                debug_assert!({
                    println!("txid={} skip={}", txid, skip);
                    true
                });

this piece of code in tx_graph.rs prints out stuff when run in dev profile. That's pretty annoying tbh, I don't think it's uncommon for people to use CLIs in the dev profile and this messes up with stdout for these CLIs.

I reckon this has something to do with debugging, but I think there must be better ways to get these kinds of printouts without bothering users?
