fix for issue https://github.com/duplicati/duplicati/issues/4666
Same logic as at powershell verify file (at line 78 in ps1)
Credits for code "ts678" in Duplicati forum
I tested it and test output fir json with error 5 is now same as in powershell verify
This leaves the current program behaviour as close as possible to the original behaviour
(with the exception of the byte by byte feeding to the hash algorithm which was probably
a bug)
* Increase block size ro 8MB to make the process faster and still light on
memory on a low memory machine
* Added a --quiet argument to reduce very verbose output.
Still needs a work over in terms of error handling, progress reporting, warning output, refactoring etc.
Also misses the volume reuse/reclaim algorithms.
But it passes the unit tests now, with and without a local database.
