使用AS3输出ByteArray为16进制

代码很烂，高手勿喷。

使用方法：

var bytes:ByteArray = new ByteArray;
bytes.endian = Endian.LITTLE_ENDIAN;
bytes.writeMultiByte("ABCDEFGLKAJSFKOIJOIJWELKJLJOI114asdfasdfasdfasdfasdfasdfaf", "utf-8");
bytes.writeInt(100000);
Byte2Hex.Trace(bytes);

Output

        4c 4b  4a   4b 4f        ABCDEFGLKAJSFKOI
 4a 4f  4a   4c 4b 4a 4c 4a 4f           JOIJWELKJLJOI114
                       asdfasdfasdfasdf
           a0    .. ..       asdfasdfaf †
