/* Update the RGB LEDs. rgb is a pointer to an array of up to 54 * 3 = 162 bytes.

   Mario & Sonic at the Tokyo 2020 Olympics Arcade uses one board with 15 LEDs for
   all buttons, control panel, and floor LEDs. Board 1 is just used for the
   left and right monitor LEDs.

   Board 0 has 54 LEDs (GRB order):
      [0]-[26]: left monitor LEDs
      [27]-[53]: right monitor LEDs
   
   Board 1 has 15 LEDs (RGB order):
      [0]: left blue LED
      [1]: center yellow LED
      [2]: right red LED
      [3]-[5]: left control panel LEDs
      [6]-[8]: right control panel LEDs
      [9]-[11]: left floor LEDs
      [12]-[14]: right floor LEDs
   
   Each rgb value is comprised of 3 bytes in G,R,B order for board 0 and R,G,B 
   order for board 1. The tricky part is that the board 0 is called from app and 
   the board 1 is called from amdaemon. So the library must be able to handle both 
   calls, using shared memory f.e. This is up to the developer to decide how to
   handle this, recommended way is to use the amdaemon process as the main one 
   and the app process as a sub one.
