Minecraft Ore Cube Lamp

Gift for my Grandson ... delivering today :)

Remix of Remix. Loved the design - changed only a couple of minor things.

I remixed the base plate to reflect the way my rigid 3 x 8 LED strips would mount, and added a small support piece for connectors to attach firmly.
Also, I rewrote the code so that by default it cycles through 16 colors (one being off), and freezes on a color indefinitely when the button is pressed. Press again to resume cycling.
The colors I chose are shown, but I may change over time as some of them look a bit too similar.

Note : I use PlatformIO IDE so have attached code as a text file instead of Arduino IDE .ino.
