Print the message in the same colour as the level

[binarykitchen]

Great library, I just ditched Bunyan & Winston for it, sorry.

As a very visually oriented person (Deaf), I would like to have the message in the same colour as the level has its colour.

I mean, if it's an ERROR, all should be printed in red. Not just its level, everything. Winston's pretty log does this.

For example, the screenshot in your README:

I think this should be somewhat configurable and default. Because if an error happens on production, all should be in red, not just the five letters E.R.R.O.R :)

	This module provides a basic [ndjson](http://ndjson.org/) formatter to be used in __development__. If an
	incoming line looks like it could be a log line from an ndjson logger, in
	particular the [Pino](https://getpino.io/) logging library, then it will apply
	extra formatting by considering things like the log level and timestamp.
