Change DownloadManager.download to use Uint8Array-data

Browse source 
Part of this code is really old and pre-dates general availability of things such as `Blob` and `URL.createObjectURL`. To avoid having to duplicate the Blob-creation in the viewer, we can move this into `DownloadManager.download` instead.

Also, remove a couple of unnecessary `await` statements since the methods in question are synchronous.
