Migration to micropython 1.21 for S3 camera firmware

• Migration to micropython 1.21 for esp32 S3, for the others I remain on version 1.20 because due to unresolved link problems.
• Added property on camera initialization (fb_location, grab_mode).
• Renaming camera firmwares, there is one firmware for esp32, and one for esp32 S3, they are generic but require modifying the main.py to choose the type of camera.
• Added support for a new camera "Seeed Studio XIAO ESP32 S3 Sense", I was able to obtain a web streaming video image, but I did not have time to configure the SD card, the two cards died successively, the first lasted an hour, the second 10 minutes. I don't know if it's bad luck, it should be noted that it heats up enormously, which may be the cause of their death. Note that I have an esp32cam board that has been running for over 3 years, outdoors in temperatures from 50 degrees to -10 C°, I understand that it dies, but it is still there. I think this is a board to avoid
