-Improved handling of some more cases of unorthodox, although valid, FileAlignment and SectionAlignment values and combinations of those
-Added a method to peutils to scan for PEiD signatures in user-provided raw data as opposed to only allowing pefile.PE() instances, it comes handy when feeding data from other tools like IDA
