Using `void*` doesn't appear to work (and looking at the 
generated wasm it seems to reduce it to `i32`, which is not the 
right type unfortunately). I guess what I could do is have a 
global array in js which stores all objects I'll need to access, 
then just access them via the index into that array but that 
feels like a hack especially when `externref` is a thing that 
exists.
