Great PR, thanks for this! 💖

Calling out @WKFO for testing, it is a core library so we need to make sure everything works properly.

I did try to build libopenmpt, but it crashed on _openmpt_module_create_from_memory. May be it was an unstable branch... Finally, I tumbled to check out the modarchive.org. The libopenmpt from this urls:

• https://modarchive.org/style/js/libopenmpt.wasm
• https://modarchive.org/style/js/libopenmpt.js

So are we using the same libopenmpt as modarchive?

[Cthulhu2]

Yes.
