Worthless

This is an experimental WASM based system to build a basic JavaScript execution system. Longer term the desire is to enable non JavaScript execution as well, but for now the runtime environment only permits basic JS execution.

Current status: this is an experimental project to establish the viability of WASM module execution in the Sentry pipeline.

• worthless-js-rt: this is a high level WASI compatible JS runtime environment based on quickjs
