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
