新增了檔案切割和重組，遇到來源中斷也可以切換source,新增進度條
，基本上如果tracker做成搜尋的樣子(不難，實現一個foxy 也是蠻好玩

整體流程就是跟一般bt差不多，client 上傳檔案分享，tracker 的seederlist 會記錄各個client傳送過來的種子檔(紀錄client要分享的檔案位置和port),當有另外一個client想下載檔案，client就會詢問tracker 然後 tracker在把seederlist可用的cleint在傳給使用者。
目前改動傳輸的檔案不再是單一檔案，類似可以中斷下載，這樣後續如果各個分割檔案都分享出去，那麼就不再侷限只能分享一個檔案，可以分享一個檔案的chunk ,這樣檔案來源應該不容易死。

實測確實binary合併後可以正確執行.
新增了檔案校驗的md5檢查，本來想選crc32的，後來發現作者本來就有引用openssl的lib
