suggestion: Respect fPetrolTankVolume and don't fill to 100

[MauroNr1]

Currently, when you fuel any vehicle, even bicycles, they will fuel up to 100 instead of respecting the fPetrolTankVolume field in the handling file. fPetrolTankVolume should be the actual volume the petrol tank can contain, for a bicycle, this is 0, jetski: 2, T20: 65, Bulldozer: 100. I presume because fueling was never implemented (at least not to my knowledge) in GTA V itself, that this system is so weird and doesn't actually respect fPetrolTankVolume.

You can check this yourself:

lib.onCache('vehicle', function(vehicle)
    print(GetVehicleFuelLevel(vehicle))
    print(GetVehicleHandlingInt(vehicle, 'CHandlingData', 'fPetrolTankVolume'))
end)
