websnark/test/groth16.js
Micah Zoltu f0ddbf34b3 Adds esbuild & Dockerfile, skips a failing test.
* 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.
