This file causes tsc to fail (even in normal compiles)

Workaround since normal builds still work here

Upgrades our build scripts to target ES2017 since they are run on modern versions of node

This allows us to remove shims for es6 features such as `Object.assign`, and also remove a few extra typings packages
