LZ编码

说明：  LZ 系列算法用一种巧妙的方式将字典技术应用于通用数据压缩领域，而且，可以从理论上证明LZ 系列算法同样可以逼近信息熵的极限。 实现LZ算法且实现GUI界面
(The LZ series algorithm uses a clever way to apply the dictionary technology to the general data compression field. Moreover, it can theoretically prove that the LZ series algorithm can also approximate the limit of information entropy. Implement the LZ algorithm and implement the GUI interface)
