Request for trucks to drive backwards

Issue description

When limited to one cell, trucks drive into the wall when turning around
An average excavator with a bucket also does not fit in one cell (I mean that visually the bucket goes through the wall)

Expected behavior

1. Add trucks to reverse in a straight line until they can turn around without hitting walls
2. Expand the ability to turn the bucket with two cages for an average excavator

Game version

v.0.4.10

This will also happen if you use the dump feature to create a single tile width path over the ocean.
I saw one of my trucks drive under water and on the side of the path to turn around.
It really should just back up.

Not planned: trucks reversing would need a different vehicle movement model.
