Chromedriver

This is a simple package that downloads Chromedriver and provides a node api for accessing the path to the binary. We want to keep this with minimimal dependencies.

How to use?
``node
const driver = require('@sitespeed.io/chromedriver');

const binPath = driver.binPath();
// launch chromedriver from binPath
`

You can override where you download the Chromedriver by setting process.env.CHROMEDRIVER_BASE_URL. You can skip downloading the Chromedriver by setting process.env.CHROMEDRIVER_SKIP_DOWNLOAD.


You can download another Chromedriver version by setting process.env.CHROMEDRIVER_VERSION.

`
CHROMEDRIVER_VERSION=81.0.4044.20 node install.js
``

If you don't set a version, the version in the package.json is used.
