ZlpFileInfo and OpenRead method

[Vahid Nasiri]

Hi, Thanks for this great work.
This library has not ZlpFileInfo.OpenRead method.

        public System.IO.FileStream OpenRead()
        {
            return new System.IO.FileStream(
                ZlpIOHelper.CreateFileHandle(
                    _path,
                    CreationDisposition.OpenAlways,
                    FileAccess.GenericRead,
                    FileShare.Read),
                System.IO.FileAccess.Read);
        }
