26-03-27 Track Week Kart Stand running

'Final' code that was attempted to be used during the EVC-A26 Track Week.
Ran successfully on a kart stand under RC control.

Working:

• CAN TX for ADCB -> Rubik Pi 3
• PWM output to control servo and throttle
• RC IBUS reading system (circular dma + sync finding + disconnect
  logic)
• RC estop
• Debounce controllers working
• Contactor closing (we hope precharge sequence has been working)

Known issues/todo:

• CAN2 RX is not working. The fix is likely routing the CAN2 filters
  through CAN1
• Dynamic PWM enable <-> Hi-Z does not work. Temp solution: commented
  logic out.
• LED blinking is does not look correct.
• Update README with IBUS info
• Clean up magic numbers in RC throttle handling
