1131002-udpcast-test07-可行版加上可以手動選擇網卡

1131014

-新增，使用者可以手動選擇網卡

-修正進度條的狀態

--可再修正

-port 常數： 將端口號（如 8500 和 8510）定義為常數，這樣有助於未來的維護和修改。 

文件路徑處理： 對於 udp-sender.exe 的路徑，建議使用 os.path.join() 確保不同操作系統的兼容性。

多線程安全： 若使用多線程來更新 UI，確保適當處理線程安全問題，例如使用 queue.Queue。

使用 os.path 時的錯誤處理： 在檔案處理中，對於某些情況下（例如檔案不存在），建議增加適當的錯誤處理來避免程式崩潰。

UI 更新： 在進行長時間的操作時（如檔案傳輸），建議使用 tkinter 的 after 方法或執行緒來保持 UI 的響應性。

代碼可讀性： 將較長的函數分拆成較小的幫助函數可以提高可讀性。例如，檔案傳輸的邏輯可以分成多個函數進行管理。
