Allow selecting the image resolution instead of "small/midium/large"resolution_improvement
The concept of small, midium, large is relative, as it depends on whatever the camera supports. Instead of using it, it is a way better to show a list of the supported resolutions. That works fine for most cameras, with uses a fixed set. On cameras with a scale, the Kernel actually exports the resolution range. On this case, let's present 4 resolutions between the minimum and maximum one. That should be reasonable for most usecases. Nowadays, all drivers should be reporting resolutions via VIDIOC_ENUM_FRAMESIZES. Yet, as one might run camorama with very legacy kernels, provide backward support, using small/midium/large resolutions just like before.
