Vector math node for compositor

So what always bothered my, is that we have a vector math node in the shader and geometry nodes editor but not in the compositor, meaning that when doing maths with the rgb channel i always have to seperate the channels and then the math operation then combine again, which for large node setups can become quite tedious.

So my idea is very simple and easy to implement, which is simply to bring the vector math node over to the compositor.
