----------------------------------------

Thank alot [~binhawking], I've quick look on your fix. Effectually, there's quite a lot of
changes. After cleanup & fix some minor, I broke CHM tests.

We appreciate really your contribution and we should continue & finalize. I've created
new pull request basing on a branch with your fix + my cleanup:

> If an embedded file contains aligned blocks, the parser outputs chaotic text or empty
text as to this file.
> I have fixed it myself, corrected decompressAlignedBlock() and its preparation methods.
Mostly this bug is due to misusing main tree/align tree/length tree. And some tree is built
wrong.
