Use `VecDeque::truncate_front` once stable

VecDeque::truncate_front isn't stable yet.

https://github.com/rust-lang/rust/issues/140667

Instead we do VecDeque::rotate_left followed by a VecDeque::truncate.

That is surprisingly fast.

Still, once stable, we should switch to VecDeque::truncate_front.
