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.

-# Fork
-
-This is a fork of the version of websnark that is used in the Tornado Classic UI.  The changes here only seek to remove as many dependencies as possible, and make the project bundlable with a simple bundler like `esbuild`.  A Dockerfile is included to facilitate deterministic builds of the generated `bundle.mjs` file.  You can generate and extract the bundle file by doing:
-```
-docker image build --tag temp_image .
-docker container create --name temp_container temp_image
-docker container cp temp_container:/websnark/build/bundle.mjs bundle.mjs
-docker container rm temp_container
-docker image rm temp_image
-```
