  方法名稱：GetSiteOMR
  引用相依：GetSiteOMR, FindPoint, Get_OMR, LoadFromFile
  方法描述：在指定影像文件的特定座標執行 OMR (光學標記辨識)。核心邏輯包含：
            1. 檢查並載入影像檔（若尚未載入），並呼叫 ClearLine 初始化黑白緩衝區。
            2. 讀取影像的 DPI 與寬高資訊。
            3. 使用 CM_Str2Rect 將 Site 字串轉為 TRect 矩陣，並參考定位點 (UpLPoi
            nt) 進行位移計算。
            4. 限制辨識區域座標不超出影像邊界。
            5. 呼叫 Get_OMR 對黑白圖形緩衝區執行辨識並返回結果值（通常為 1 或 0）。
            此方法是自動化資料檢核的重要工具。
