Migrate deque from denque to Js-sdsl Deque

Hey! I'm the developer of Js-sdsl. Official website: https://js-sdsl.github.io/.

Now, we published the version 4.1.4.

I see you are using denque.

In benchmark, we have confirmed that Js-sdsl is several times faster than denque and nearly equal to Array.push in the case of push elements.

We would like to invite you to migrate deque related functions to Js-sdsl v4.1.4 and I am willing to submit a pull request for this change.

Looking forward to your reply! :D
