Crash in FRUA spec code when clicking on Treasure game.ovr

description

GBE crashes is the FruaGlbFileSpecifcation trying to read the reader.ReadChars(4) as it treats the data as RTF8 string.
 
So as it's a byte string just, read a Uint, and then compare to the "text" equivalent in hex (but reversed) like so:
 
                //var headerText = new string(reader.ReadChars(4));
                var headerText = reader.ReadUInt32();
                var fileSize = reader.ReadInt32();
                var entries = reader.ReadInt32();
                //var dataText = new string(reader.ReadChars(4));
                var dataText = reader.ReadUInt32();
 
                return headerText == 0x42494C48 /* "HLIB" */ &&
                       dataText == 0x41544144 /* "DATA" */ &&
                       fileSize == new FileInfo(parameters.FullPath).Length;
 
also move the second string compare before to file size read, as the later is more costly.

You also want to add a
            if (stream.Length < 16) return false;
at the start to avoid small files

Applied the change here (and in patch 7221) minus the comment lines.
