Small timeout fixes

[dbulos5]

corrected timeout_length function, added description to differentiate between module and inverter timeout, added 'inCar' to Inverter timeout arg to remove redundant faults

Looks fine the main issue is we need to update our DBC and maybe even modify the packStatus message to give us the module and timeout length in CAN, I'd also rename getMaxCanTimeout() to getMaxInverterTimeout() to avoid confusion

[dbulos5]

I made the function name change. I didn't want to touch pack status since it's nearly full, and i'm assuming you already have an idea to handle the CAN.

@yamaan93 I've now verified on charge cart and in car
