Control of various group flashing using millis and arrays for length/interval

This sketch uses an array/millis based LED control with a button to select flash sequences. The button sketch works well, with pull-up pins and millis. Then to progress and replace the button with a rotary encoder from another sketch, and then to develop that to use an OLED display and a menu to select from. The rotary encoder sketch is written and operates using its own library Rotary.h and interrupts. The final sketch will be used to display lighthouse characteristics, names and data via LED and OLED screen.
