Moves to a forked version of the terser plugin because the jest-worker dependency is causing trouble.
This also moves to yarn2 as a requirement for the simple reason that this is what is being used during deployment. The main difference is that the yarn.lock file now comes in the yarn2 format. Classic yarn should still work fine if you run yarn install before compiling/running and be careful not to commit the resulting yarn.lock.
