Feature Idea: Press M5 Button to add +1 to Camera

[Fred-DTV]

Hi,

I had this idea where you can press the m5 Button (BtnA) to scroll through the camera channels.

I've tried different ways to implement this myself but i couldn't get it running.
M5.BtnA.waspressed()
M5.BtnA.ispressed()

if (M5.BtnA.wasPressed()) { cameraNumber = FSM + 1; FSM++; if (FSM >= 4) // set max number of camera in this case 4 FSM = 1; }

Both didn't work for me.

Maybe someone else is luckier than me.

I've put put in a PR to solve this issue. I've tested this on an M5StickC and it's worked quite well.
