This section details on the original issue you should resolve

<issue_title>Left side of screen still not displaying previous page, displays next same as the rest of the screen</issue_title>
<issue_description>calendash-api.py still not working.

I have an idea, tell me if it's stupid. What if there was a completely separate script that would only display the picture like the placeholder scripts did. I'm sure that would save a significant amount of memory and cpu long term.

In short:
calendash-api.py pulls the data draws the display and saves the image everyday at 6am
(we would need to exclude it like piholestats_v1.2.py).
It runs completely separately to the rotator and it's children scripts.

calendash-img,py displays the image and waits for a touch or for the set amount of time to pass before shutting down. </issue_description>
