Add binary search to Nim track

[razvbir]

This is my first pull request here, not sure if what I did is correct. I can also provide a solution that doesn't use std/algorithm. All I know about configlet comes from here.. Not sure if I've used it right.

Hello. Thanks for opening a PR on Exercism. We are currently in a phase of our journey where we have paused community contributions to allow us to take a breather and redesign our community model. You can learn more in this blog post. As such, all issues and PRs in this repository are being automatically closed.

That doesn't mean we're not interested in your ideas, or that if you're stuck on something we don't want to help. The best place to discuss things is with our community on the Exercism Community Forum. You can use this link to copy this into a new topic there.

Note: If this PR has been pre-approved, please link back to this PR on the forum thread and a maintainer or staff member will reopen it.

Hi. Thanks for the PR, but community contributions are indeed paused. Sorry about that. We should have made this more visible to newcomers. I've created and pinned #494.

But in any case, I've already implemented this (and a lot of other stuff) locally, and self-assigned #490. It's coming soon. Reviewing and going back-and-forth on this PR would make it take longer - sorry.

Hope you can still enjoy the Nim track. A long-overdue upcoming change is that we'll soon provide each exercise with a stub solution. Should make things a bit nicer.

Thanks again.

The binary-search and linked-list exercises are now available:

• https://exercism.org/tracks/nim/exercises/binary-search
• https://exercism.org/tracks/nim/exercises/linked-list

we'll soon provide each exercise with a stub solution

Also done.
