enhance lane output to make it easier to compute the total number of vehicles (trac #1829)

[behrisch]

there is currently no way to accurately count to total number of vehicles that passed a lane without the risk of counting lane-changed vehicles multiple times.

Edge output does not have this issue since every vehicle is either in 'left' or 'arrived' (and in 'entered' or 'departed').

One could argue that is simply the wrong tool for that and to use a real detector instead.
