Title: Enable colouring (ie via ansio)

This will enable colouring (example with and without)

![example](https://s3.amazonaws.com/josh.cheek/images/scratch/willful-with-ansio.png)

It works by allowing the user (or lib such as [ansio](https://github.com/JoshCheek/ansio)) to define `Sequence fgRed` and `Sequence fgGreen` as appropriate for their system. If these methods are not defined, it defines them such that they do nothing.

The user will have to manually add the lib or methods in their test helper. If they are using ansio, that would look like `doFile(System ioPath .. "/ansio.io")`
