Note: Digit positions for showSegments() depends on the order in which the segments

from the right side when seen from the front, TFO from the left. Others may have different
orders, like Lazy 7 - QBE, which is using a single strip and has an order of
3, 0, 2, 1 for top left, top right, bottom left, bottom right.
"The Final One(s)" is starting from the left when looking at the front, so it's
exactly the reverse order of the old/other ones. This doesn't really matter, that's
what "digitPositions" a few lines below is for...

/* Below is the configuration for led <> segment assignments.
LED_ACCESS_MODE 0 will use the two values inside each segment (led a, led b)
as they are - 2 leds per segment.
LED_ACCESS_MODE 1 will use the two values inside each segment (led a, led b)
as start and end value to get 2+ leds/segment.
Example:
leds 0, 3 -> MODE 0 -> led 0 and 3 inside the segment -> 2 leds
leds 0, 3 -> MODE 1 -> led 0 - 3 inside the segment -> 4 leds
Simply add all the leds into their corresponding segments inside the array.
The order of digits/strip routing doesn't really matter there, positions of
HH:MM:SS are assigned using digitPositions.
