Function write_to_test_logs

fn write_to_test_logs<S>(line: S, bypass_test_capture: bool)
where
    S: AsRef<str>,

Write line to stdout, so it can be seen in the test logs.

Set bypass_test_capture to true or use cargo test -- --nocapture to see this output.

May cause weird reordering for stdout / stderr. Uses stdout even if the original lines were from stderr.
