standalone version (similar to wasm2js)

How much sense would a standalone version of this make (in comparison to [wasm2js](https://github.com/WebAssembly/binaryen#wasm2js))?

Currently this library heavily relies on `new Function` which is blocked by our CSP, so we're wondering which would perform better when compiled ahead of time. We also use Go for our binaries, so the Go-specific optimizations seem interesting.

Guess this might also be too much of a rework to be worth it 🤷.

Thanks in advance!
