adding objdetect for esp32

I'd like to use objdetect, so I tried to add that, however the build fails in a new way, related to insn.
I'm using esp-2021r2-patch3 to overcome #11
Is there a recommended version to build this library?

I also tried esp-2020r3, which had the same failure. I cannot go back any farther as this is the first that supports esp32s3.

in build_opencv_for_esp32.sh :

OPENCV_MODULES_LIST=core,objdetect
