`get_same_blocks` is a helper to compare two files and return a list of the blocks that are clones of each other. Its very necessary for block cloning tests. Previously it was incorrectly called `unique_blocks`, which is the _inverse_ of what it does (an early version did list unique blocks; it was changed but the name was not). So if nothing else, it should be called `duplicate_blocks`. But, keeping the details of a clone operation in your head is actually quite difficult, without the additional overhead of wondering how the tools work. So I've renamed it to better describe what it does, added a usage note, and changed it to return block indexes from 0 instead of 1, to match how L0 blocks are normally counted.
