Does napi default to true or false? Docs think false.

prebuildify/README.md

Line 86 in d6d6981

| `--napi` | - | `false` | Make [Node-API][node-api] build(s).<br>Targets default to latest node which is compatible with Electron > 3, which can be overridden with `--target`. Note: `--all` should be avoided for now because it includes targets that don't support Node-API.

This line is incorrect as far as I can tell:

prebuildify/bin.js

Lines 22 to 24 in d6d6981

	default: {
	napi: true
	}

Which caused me a lot of confusion until I discovered the following through some local debugging:

#64 (comment)

prebuildify is geared towards Node-API, so the version of the executing node process is not necessarily the right version. It defaults to compiling against the latest node version

The default recently changed in 4300cf4 and we forgot to update the README. That should say true. PR welcome!
