Description

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.
