Open Loop Idle and Cruise

Decided to Make a patch to force open loop at idle and while cruising.

To read the Logic look on the right. Pretty simple. Also allows Hiway Mode Spark to keep working.

Let me know if you think anything else should be added.

Edit: Added a KR check that if above a threshold it will enter closed loop and clear the hiway timer which would drop timing back down based off your hiway spark adder table.
