All in one trenching vehicle

Add a new vehicle that can dig one unit down, lay pipe, then cover the trench back up all in one pass. Similar to how Tree Harvesters can have trucks assigned to them to collect wood, this trenching machine can have other trucks deliver it material to construct pipes. The trencher can come in two sizes, small and large. The small trencher can dig 1-4 tiles wide and lay 1-4 rows of pipes. The large trencher can dig 1-8 tiles wide and lay 1-8 pipes simultaneously. In the trenching machine UI it can have a drop down toggle to select how many tiles wide to dig and then a separate drop down to select which tier of pipe to lay. In practice, the trencher will continue along its designated path as long as it is continually supplied with the proper construction parts and (steel). Attached is a quick generated image to visualize the concept.

I also considered using buried pipes more. Visualization of the buried pipes would be useful though or at least being able to mark the land by some color in a "pipe layer" similar to planned buildings.
