Feature Request - Setting for priority and addition to readme

[moose-on-road]

Hi, something that would be helpful to amateurs like myself, could you implement a "stepper.setTaskPriority" along the lines of how core selection was added?

i found bumping this up solved my jittering issues, and reading through some discussion it has helped several other folks. If you know what youre doing, it only takes 2 seconds to find and change the setting, but it took a lot of reading to figure out that changing the setting would be helpful, so maybe a row could be added to the decision matrix.

@moose-on-road can you provide some input for the readme please since you did all the reading already?

If there was an option to set the priority, the decision matrix could include another row:
Decision matrix:
Scenario :
appropriate core selected, jittering still present
Suggestion:
change setTaskPriority() to 2
