resolve v1.17.0 on node v12.16.1

[kumavis]

as a workaround I'll just use the node builtin resolver

const { resolve } = require("module").createRequire(process.cwd());
resolve("./config")

This is intentional; you can provide it in the extensions option. See #137 as well.

Closing in favor of #166.
