Issue in decoding 0xFF in Unsigned Integers and Strings context

[fdur]

In Unsigned Integers and Strings context, 0xFF indicates a 32 bits unsigned integer
In decodeUintsAndStrsObject, the returned value is an int64 instead of uint32

[fdur]

Simply update decodeUintsAndStrsObject from

 	case opcode == 0xFF: // Very large unsigned integer (> 135274635)
 		var n uint32
 		err := binary.Read(d.reader, binary.BigEndian, &n)
		return int64(n), err

to

 	case opcode == 0xFF: // Very large unsigned integer (> 135274635)
 		var n uint32
 		err := binary.Read(d.reader, binary.BigEndian, &n)
		return n, err
