Open Source Sequential Shift light V3.1 Improvements from V3 include

• Upgraded, Faster LEDs (APA102C Dotstar) replace old WS2812B

• New Animations (out-to-center now included)
• Optimized code and calculations
• Auto-shut off
• USB output and dim icons

• Add "profiles" for settings (ie, normal driving, track, drifting, drag, etc)
• in Debug mode, clean all other serial.print data so it's just RPM output in all instances
• Add more brightness resolution, or make existing scale more dramatic
• Add a run-time "hour meter" option in the menu. Test to see if an RTC chip is needed.
