Enhancement - New Effect - Stepper total position tracking

[MirageC79]

Description: Similar to [Stepper] effect, but instead of having a dot with blends on each sides, this effect would track total distance from axis "Zero" to the current position. Then using the defined max position of the axis the ratio of number of LEDs from the start of the strip to be activated is defined.

Application: I am trying to have vertical LED bars (SK6812s) on each sides of my CoreXY printer's Z axis. At first(Z0) all LEDs would follow a certain effect to create an ambiance under the print bed. As the print progresses, LEDs from the top of the bars would start to light up with a different effect (White) following the print bed. This way, only the printed part receives full light, while the area under the bed keeps its ambiance lighting.

Thank you ☺ And once again! fantastic work! 💯
