Implement new learning exercise: `partition`

Read the linked v3, rationale, and concept-exercise docs before starting, then inspect existing exercises under languages/clojure/exercises/concept for their structure. Create the listed .docs and .meta files plus the exercise and test files for partition; completion means the exercise teaches the stated concepts and its tests and documentation follow the track conventions.

This issue describes how to implement the partition learning exercise for the Clojure track.

Getting started

Please please please read the docs before starting. Posting PRs without reading these docs will be a lot more frustrating for you during the review cycle, and exhaust Exercism's maintainers' time. So, before diving into the implementation, please read up on the following documents:

• The features of v3.
• Rationale for v3.
• What are concept exercise and how they are structured?

Please also watch the following video:

• The Anatomy of a Concept Exercise.

Goal

The goal of this exercise is to teach the student how the partition function can be used in Clojure.

Learning objectives

The student will gain a general understanding of:

• The power of Clojure's sequence functions to transform data in contrast to imperative loops and recursion.

For a perfect example, check out these Clojure solutions to a very simple Advent of Code problem: https://www.youtube.com/watch?v=3w0FWqGC0PM

These solutions have also been gathered into a gist

Implementing

To implement a concept exercise, the following files must be created:

languages
└── clojure
    └── exercises
        └── concept
            └── <SLUG>
                ├── .docs
                |   ├── instructions.md
                |   ├── introduction.md
                |   ├── hints.md
                |   └── after.md (optional)
                ├── .meta
                |   |── design.md
                |   └── Example.clj
                ├── <NAME>.clj
                └── <NAME>_test.clj
