Add an option to align nodes

[Flowwl]

Hi 👋 ,

I am using the lib for personal purposes and I love it 😄,

In my project, I just implemented a way to align nodes between them that would look like this :

It works with a setting option that can be activated/deactivated and with a DELTA which determines the sensibility of the trigger

I was wondering if some people would be interested in this feature and if I could implement it

This feature would be really useful as we also want to implement something like this in our project but have no idea as to how to begin
