Verify Upload by Downloading and Comparing Hashes in Parallel with Uploading

[DavidBerdik]

To ensure the integrity of uploads, we should add support for downloading newly-uploaded fragments in parallel. This way, we can catch any corruption before it occurs. Our current approach for error detection and correction, while superior to earlier versions of the program, is still imperfect. This would require redownloading an entire upload in the background, which is of course slow and not ideal, but it is unfortunately the only way we can truly be sure that the Drive API has not corrupted it.

Due to upcoming changes to Google Drive's storage quota rules resulting in the end of InfiniDrive development, this issue has been closed without completion.
