- Add n4 parameter support to main.py ESP NOW receiver - Implement segmented_movement pattern with configurable parameters: * n1: segment length (number of LEDs per segment) * n2: spacing between segments * n3: forward movement speed (positions per beat) * n4: backward movement speed (positions per beat) - Pattern alternates between forward and backward movement each beat - If only n3 or n4 is set, moves in that direction every beat - Draws repeating segments with spacing across entire LED strip - Add Pipfile script to run dev.py directly with arguments
