Improve install speed and size

[bencoveney]

package.json is getting fairly large - can we trim anything out?

> npm install
...
added 1195 packages from 808 contributors in 157.752s

> npm test
...
webpack --config webpack.prod.ts --mode production
...
Time: 32929ms

Webpack dev server performance is still fairly good 👍

Could try npm dedupe and npm shrinkwrap.
