Emscripten version 3.1.42 and up cause errors in the js output

[NTM-Adam]

When compiling patches with emscripten versions > 3.1.41, the outputted js wrapper throws errors such as the following:

Converting base64 string to bytes failed

Upon debugging, it appears there was a reference error around the atob() function, previous versions included a fallback for this function in the compiled output.

Hmm, possibly we just need to add it to DEFAULT_LIBRARY_FUNCS_TO_INCLUDE section?

This possibly got fixed here: emscripten-core/emscripten#20587

@NTM-Adam did you get a chance to try latest emscripten yet?

[dromer]

Hmm, I just tested with 3.1.50 and I still see ReferenceError: atob is not defined in the console.

[edit: ok I figured it out from some posts on the emsdk issue tracker: we need to add shell to the AudioLibWorklet emcc ENVIRONMENT and then it works!]
