📄 Description

I've added support for built Tesseract 4.0.0 in Windows - http://www.ccextractor.org/doku.php?id=public:general:tess_build
It was necessary only to update the code in one place - in hardsubx_classifier.c, so what works well both on Linux and Windows
Also I updated old zlip and libpng (dependencies of tesseract) to avoid errors

Known issues:

Built executables requires .dll files with names starts with "pvt.cppan.demo." (different for Debug and Release). I have not figured out yet how to fix it. Download DLL Also, while it is not fixed, I do not copy DLL files after build in folders

I'll fix this issues in later commits
