User seems to have lost interest, so recovery tool will not be pushed further until someone cares.
Below is what there is so far, and it might have other uses, e.g. if other restore methods disagree.
This one is very straightforward partly because it has to NOT read dlist. It reads dindex blocklists,
basically taking care of the problem of how to put blocks in right sequence to make the large files.
It also has the user do some manual decrypt and unzip. Some duplicates might occur, but ideally
the content of the same file name is the same. If any difference is seen, that would be concerning.
It grew up on Windows (which surprisingly does have a tar command), but is probably portable…
