find_magic 功能
V831提供find_magic 功能，为识别魔方色块的，将魔方放在识别框中，可以自动识别出每个框所对应的颜色。
文件地址 ：https://github.com/sipeed/MaixPy3_scripts/blob/master/application/maix_cv/maix_cv_find_magic.py
参数说明使用maix_cv.find_blob_lab函数实现
maix_cv.find_blob_lab(pic,lab,tilt=0)
| 参数 | 说明 |
|---|---|
| pic | 240*240 尺寸的图片的 RGB Bytes 数据 |
| lab | lab阈值数组，[l_min, a_min, b_min, l_max, a_max, b_max] |
| tilt | 斜度选项，缺省为 0 |
