Implement new Concept Exercise: overflows

[ErikSchierboom]

This issue describes how to implement the overflows concept exercise for the F# 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 the basics of the Concept of Memory Allocation in F#.

Learning objectives

• Explain integral number overflows.
• Explain floating-point number overflows.
• Know how to use the Checked module to deal with overflows.

Out of scope

• BigInteger

Concepts

The Concepts this exercise unlocks are:

• overflows: explain integral number overflows; explain floating-point number overflows; know how to use the Checked module to deal with overflows.

Prequisites

This Concept Exercise's prerequisites Concepts are:

• integral-numbers: know about the integral number types.
• floating-point-numbers: know about the floating-point number types.
• exceptions: explain how an OverflowException is thrown when using checked arithmetic.

Any data types used in this exercise (e.g. strings) should also be added as prerequisites.
