測試目的

1-8通道取n個數組合，測試不同組合場景執行邏輯正確性

實現1：列舉法

 2     """
 3     1-8通道任意2通道組合扎取
 4     """
 5     # 方法一：列舉法

 7         for b2 in range(a2 + 1, 9):
 8             load_tips({"Sequence": "Lane7TipsPos1", "Channels": [a2, b2], "IfIncrement": False})

10     reload_sequence("Lane7TipsPos1")

實現2：Python標準庫itertools
