This tool is used to increment the elevations in a digital elevation model (DEM) along the boundaries of a vector lines or polygon layer. The user must specify the name of the raster DEM (`dem`), the vector file (`input`), the output file name (`output`), the increment height (`height`), and an optional breach lines vector layer (`breach`). The breach lines layer can be used to breach a whole in the raised walls at intersections with the wall layer.

## Function Signature

`def raise_walls(self, dem: Raster, walls: Vector, breach_lines: Vector, wall_height: float = 100.0) -> Raster: ...`
