   The burn-in effect is when you can see the previous picture on the screen faded in the background.
   It is not unusual or defect, it's normal behaviour of e-paper screen.
   Nevertheless, sometime the burn-in effect can be too strong and noticeable. In that case, you can
   run this sketch to clean your screen.

   The sketch didn't help? Refrigerate your Inkplate for 60 minutes!

   NOTE: burn-in effect is much stronger at the direct sun of when exposed to heat source.
   e-paper screens are not intented to be used at strong sun and in hot enviroments.
