* Adds esbuild as a bundler. * Adds Dockerfile for deterministic building of the bundle. Important Note: The failing groth16 test fails on upstream, which means it is failing on the version used in Tornado Classic UI. This is unfortunate, but if it is a critical bug at least it isn't an escalation compared to current state of things.
