Implement a different overlay for each page

[zfdx123]

FrameCallback frames[] = { drawDateTime, drawCurrentWeather, drawForecast, drawDeviceInfo };
int numberOfFrames = 4;

OverlayCallback dynamicOverlay[] = { drawHeaderOverlay, drawHeaderOverlayTmp }; 
uint8_t overlayIndex[] = { 1, 0, 0, 0 };

ui.setOverlays(dynamicOverlay, overlayIndex); 

Configure different bottoms for different pages to achieve better custom display effects
