cam support for Freenove ESP32-Wrover and clones ESP32-Wrover-Dev

[jenswes]

Hello,

thanks for this nice project, i'm trying to bring it to run :-)

rzeldent Rene 's nice esp32cam-rtsp and maxgerhardt 's pio-esp32cam have some more esp32cam versions supported by looking into the following configs,

https://github.com/rzeldent/esp32cam-rtsp/blob/develop/include/lookup_camera_config.h
https://github.com/maxgerhardt/pio-esp32cam/blob/main/src/camera_pins.h

i would guess the following could support my cam: The board is some clone of Freenove ESP32-Wrover CAM Board (i think, it looks like)
