"no such file" error when loaded as NPM package about opus-stream-decoder

@zandaqo Have you dealt with this before? I came across emscripten-core/emscripten#5342

[zandaqo]

@anthumchris Indeed I have, it was a year ago and I chose to bundle my wasm and js into a single file with emcc — bind -std=c++14 src/wasm.cpp -s WASM=1 -O3 -o wasm.js, as done here: https://github.com/zandaqo/iswasmfast

But iswasmfast wasn't meant as a package, so I'd prefer locateFile in this case.
