Add rocket flight path planning

[O.J.Vodka]

Add rocket flight path planning, which executes the second command after completing the first task without manual operation, to know the total number of grid cells flown to prevent fuel shortages from making return trips impossible. For example, taking off from Planet A, the first target is the ice asteroid field for resource mining, the second target is the amber field for resource mining, and the third target is returning to Planet A, with a total flight of 15 grid cells.
