Actually fixes https://github.com/TurboWarp/packager/issues/528 https://github.com/TurboWarp/packager/pull/861 fixed running large projects in Chrome, but packaging still used string concatenation so it remained broken. Now the concatenation part is done using TextEncoder & Uint8Arrays and a template tag function to keep it readable. This time I have actually tested it with a 1.0GB sb3. Breaking Node API change: The data property returned by Packager#package() is now always a Uint8Array instead of sometimes string and sometimes ArrayBuffer.
