* 2019 Chrysler Pacfica and 2019 Jeep Grand Cherokee support, along with likely support for arbitrary models.
This is done by copying most values from the stock LKAS camera which is active with https://github.com/commaai/panda/pull/177
* No longer send LKAS_HEARTBIT because Panda now forwards it for us.
* Pacifica Hybrid 2018 combine fingerprints, add 808: 8
* panda chrysler: forward bus 0 to bus 2
