validator.js test for JetStream

Measures the performance of the validator.js library by running the core test suite.

Build Instructions

# install required node packages.
npm ci
# build the workload, output is ./dist
npm run build

The workload is a modified copy of the validator.js test suite. Several files are combined together and contents copied to the runTest method.

Modifications to the original:

Any tests that depend on node internal values have been removed.
Date constructions with an arg-array differs between browser and thus they are replaced by direct arguments.
Direct calls to validater.xzy() are replaced with validatorjs.xzy() to not conflict with the default argument to the mock test() method.
