+This requires that the `_decode` method can unpack the encoding back to `bbbbbc` and also know that the decoded
 block starts at 3, so that it can return just `bbbc`, as required.  Such layers therefore typically need to keep much
 more internal state, to keep track of which offset of encoded data relates to which decoded offset for both the mapping
 and `_encode` and `_decode` methods.
