Add audio to ios example (#1007)

I'm still here :) will try to land the ios audio support in cpal soon and then we can land this.

This PR also adds in assets as a directory reference and avoids the "Xcode is optimizing and breaking my PNGs" issue that I had earlier on during iOS testing on Bevy.

Re-testing this now.
