This is no longer necessary with modern editions of Rust. In many cases, we also did

Remove "extern crate criterion" in benchmark code, and update "use" statements as necessary. Along the way, remove a few unnecessary
extern crate arrowand similar from the benchmark code.Are these changes tested?
Yes, but no new tests added or needed.
Are there any user-facing changes?
No.
