Refactor the serial communication of ESP32 and Mega to be content agnostic

[Recelis]

Currently, the communication between the ESP32 is the {...weatherforecast, location, dayOfWeek} and the Arduino Mega consumes this and converts it into LCDBoxes to be displayed on the screen.

This is an issue when I want to start displaying temperature values from other ESP32Monitoring systems.

To fix this:

• generalise and standardise the communication between ESP32 to Mega.
• • This can be of the form: {box_n: [{text, size?, colour?}]}
• • • this logic will have to take place in the ESP32 side.
• • There may be a mapping needed for the ESP32Monitoring device and the box_n so that the order of the different ESP32Monitoring devices remains the same
• • • {box_n: esp32monitoring_id or esp32monitoring_mac_address (default = null)}
• On the mega side, refactor to read values in and for each line in the box_n array.
• automatically calculate the x and y positions of each box and write to the screen.
• • for box n,
• • • x = round((n % 4 ) * WINDOW_X_SIZE / 4 + X_OFFSET);
• • • y = round(n/4 * WINDOW_Y_SIZE / 2 + Y_OFFSET);

The conversion of the different data will most likely need a joining class.

Get feedback from reading in touch input on screen to 'scroll/change pages'.

add 'WeatherBox date' title to the screen.

Do this once the ESP32Monitoring sensors have been set up again.
