Issue: Zip doesn't work?

[paambaati]

I tried using the latest version of fflate, and I can't seem to get the zip() method to work.

Example CSB
https://codesandbox.io/s/fflate-zip-files-yuu21

Steps to reproduce

1. Go to the linked CSB.
2. Open the console and click on 'Upload Files'.
3. Select a few files.
4. Now watch the console not print any of the lines after zip() is called.

Additional context
I wrote a simple Promise wrapper around the callback-based zip() method so it is easier to make them work in async/await flows.

You can't use raw ArrayBuffer, you need to wrap in a Uint8Array. It seems to work for me after changing that, can you confirm?

You’re right, I did get it to work once I cast the ArrayBuffer to an Uint8Array.
