void screenRotate(DISPLAY_ANGLE angle);

Hi,

First of all, thank you for your work on this incredible module.

I have a Vision Master E213 Dev Board and am trying to rotate the screen 180 degrees. I see the function being declared in the library but it does not seem to work.

I haven't looked deep in the code yet, does it not have an implementation?

Please let me know if that's the case so I might try to contribute to the library when I get the chance.
