Hank flashlights with the kr4 driver sometimes show the wrong voltage on rgb aux only when in blinking mode

[markus]

 https://youtu.be/IEoq8qcCRFQ here is the bug in action. It is very specific in when it occurs occurring only on hanklights with the kr4 driver (firmware target either kr4, kr4 nofet or kr4 219). As the video shows it only manifests itself when the aux lights are in voltage color mode and blinky brightness mode and when the voltage is in the range where only the blue aux light should be active. Every so often the light blinks orange instead of the right color for a few blinks. It happens on all 5 of my kr4 driver hanklights when I flashed anduril2 compiled from the source code yesterday (21.07.2021)
