Describe the solution you'd like

In the worldgen that I designed before coming to OTG, there was a unique undefined feature that I haven't really seen anywhere else but I thought looked better than the normal accepted way of doing things. This of course was that biomes appear to steadily phase out over 2-3 chunks instead of having a defined line of "this is where the snow or sand ends and the grass begins". What this did is it made the world look like the snow was thawing or the sand had been flung over into the grass. My idea is that we add an option in the WorldConfig that allows preset devs to use this alternative way of blending biomes rather than have a rigid line.

Describe alternatives you've considered

We could just not do it. It's not really necessary.

Description aka Additional context

I'm going to attach some screenshots of how it looks in my worldgen so you guys can judge for yourself if this looks good.
