Feature Request: CSG-like shapers (primarily subtraction / difference operations)

[GGAlanSmithee]

It would be really cool if you could create subtraction shapes for things such as

• creating window- and door cut-outs in a WallMeshShaper
• carving a path in a forest (ScatterShaper)

In addition to this, it would be cool to support addition operations, for things such as T-shaped walls, but I suspect this is a fair bit harder than the subraction-operations.

I have no idea how hard something like this would be. I would be willing to help if you would consider something like this, but I would require guidance.

Here's are visual examples to better communicate the idea

I just re-read the README.md :

Notice that the trees above both snap to ground and ignore the footpath. This can be toggled by layer masks

so the part about carving paths in a ScatterShape is already supported - amazing!
