FCA Giorgio: Alfa Romeo Stelvio

[jyoung8607]

Resuming work on commaai/openpilot#32898.

Users have driven an earlier version of this code on both Stelvio and Giulia and seem to be loving it. The lateral acceleration torque controller feed-forward is an excellent match for these cars. There are some obstacles we need to solve for official support; it's possible we'll have to ship it in dashcam mode.

Checklist

• test route added to routes.py
• route with openpilot: TBD
• route with stock system: TBD
• car harness used (if comma doesn't sell it, put N/A): VW_A

To-Do

• FCA Giorgio: CAN database #1250
• FCA Giorgio: Alfa Romeo Stelvio panda#1980
• UDS/VIN fingerprinting
• Locate gearshift position signal
• Locate driver gas signal
• Locate cruise button signals
• Locate driver seatbelt signal
• Locate BSM signals
• Verify turn signal correctly processed (comfort vs latched, blink vs continuous)
• Plot out and test known HUD messaging (lane lines, etc)
• Fix reported issue with lane changes to the right

Jeep Renegade almost works on this port, we'll see what happens after some tweaks and updates. Renegade is derived from the Fiat SCCS Wide platform which has quite a lot of heritage predating the FCA merger. May end up renaming the port/safety to Fiat if this works out, we'll have to see how UDS fingerprinting looks.
