chore(deps): remove is-core-module dependency (#295)

* chore(deps): remove `is-core-module` dependency

Node.js from v6.13.0, v8.10.0, v9.3.0 includes `module.builtinModules` which we can use to natively check if some module belongs to Node.js core or not.

This drops not one, but _three_ dependencies, removing 70 KB of bloat: https://npmgraph.js.org/?q=is-core-module

* Simplify util

* Update index.ts

* Create spotty-grapes-draw.md
