GNCC GC2 camera. Interior and firmware change.

This time a description of the GNCC GC2 camera. The camera version on the ak3918ev300 chip is not supported by either Thingino or OpenIPC. In order to run RTSP streaming, I had to use the manufacturer's SDK and write my own software. While there is an example with RTSP, it does not have iris and IR LED control, nor does it have an OSD. In addition, I had to add button support. The only thing I didn't get right was the microphone. The camera can now be configured and used without the app. The software that works with the app I knocked out.
