Add impounding via VIN

[Pazz]

Vehicles without a physical plate on it, thus a blank license plate, cannot be impounded by law enforcement or mechanics unless it is physically broken into for forced entry, someone sits in it and runs the impound command, because you no longer need to enter a license plate when you are inside the vehicle you are attempting to impound.

This makes very little sense, especially for mechanics but also for law enforcement, so it feels like an oversight. Please make it so that a vehicle can be impounded with its VIN.
