Can't reproduce emcc build of js/dist/libshine.js

[TimDaub]

Hi,

I'm currently trying to add npm support for this package. However, right now when I go into the js folder and run make, I get a different output in dist to the one that you've uploaded.

I get a separate .js and .wasm file. I wonder if that's because we may have different emscripten versions or because there are some parameters missing in the Makefile.

Mine is:

> emcc --version
emcc (Emscripten gcc/clang-like replacement) 1.39.0 (commit ae5044e7797654f2ed5fb7c0e174e7c8ead5187b)
