Fetch returns a promise, not a TJSResponse.

See

https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/fetch

So you will at least need an async modifier if you want to have it return a
'JSResponse'

But for backwards compatibility, this cannot be added with the name 'fetch'.

So I have added it with the name asyncfetch.
