Enhaced support for VCA lane guidance / GPS

[DrewCZ]

Hi @TobiasF92 first, thank you so much for your great mod. I have a dream... :-) Please add functions for VCA lane guidance / GPS tracking. I think the most used are: "toggle lane guidance" "disable lane guidance" "switch to left reverse lane" "switch to right reverse lane"

Other functions are questions about lane setting before work and can be easily done by menu. Maybe we can call it like "nice to have" in IC.

I'm asking for support, because this lane guidance has a stronger and faster guide to the lane against the Wopster's GPS mod and additional functions like skipping lanes, switching to other lanes on a headland, etc. Thanks for looking into it. Ticho aka DrewCZ
