Enable compatibility to allow solar smart chargers to wake the car

Allow smart EV chargers to wake up the Tesla.  This will allow smart chargers to use excess solar power to charge Tesla cars.  At present, smart chargers can not wake Tesla cars, which means charging can not start.  

This behaviour is described here, specifically with a Model 3 and a Zappi charger https://myenergi.info/tesla-model-3-asleep-when-sun-shining-t810-s10.html

An example of a smart solar charger is the Zappi from MyEnergi https://myenergi.com/product/zappi/
