Examples don't render on Safari below v15

[MalbaCato]

... for a really stupid reason - it lacks the instantiateStreaming function of the WebAssembly API.

Because Apple updates the browser together with the OS, this renders it inaccessible to most Safari users.

I was able to circumvent this locally, by inserting this tiny stupid polypill snippet:

WebAssembly.instantiateStreaming = async function(f, i) {
    const responce = await f;
    const ab = await responce.arrayBuffer();
    return WebAssembly.instantiate(ab, i);   
}

Obviously care should be taken to not overwrite the method if it exists, and possibly there are problems with this that I overlooked (cause I didn't look much at all), but it shouldn't be that hard to implement.

Applies to the demos on the dedicated demo page too, of course
