sldyz compression test files

These test files have fixed sldy import problems from previous version. These are the problems tha were fixed: Import image dimensions correctly (SLDY was wrong, I added the same file as sld for comparison) Issue when thumbnail size was too big Issue when yaml file was too big Import ROI's Issues with pointers imported as 32bit sugned integers本次提供的测试文件已修复了旧版本中存在的sldy导入相关问题，本次修复的问题如下： 1. 正确导入图像尺寸（原SLDY逻辑存在错误，我添加了同一份sld文件作为对照）； 2. 缩略图尺寸过大时引发的异常问题； 3. YAML文件尺寸过大时引发的异常问题； 4. 感兴趣区域（Region of Interest，ROI）的导入异常修复； 5. 指针被误导入为32位有符号整数时引发的各类问题。
