esp32-cam OV2640 focus adjustment wrench

I'm adding a tool for fine-tuning the focus of the OV2640 camera module. Currently, I have designed a bracket only for the first 3 commonly used lenses for the OV2640. Support for OV8225 camera lenses will be added in the future.

WARNING! I am not responsible for any damage to the lens or problems caused by improper focusing of the lens. The lens is initially focused correctly for the camera module. However, sometimes it may be necessary to adjust the focus
