Returns a list of cell indices starting with start and ending at a cell
within goalTolerance of goal, or null if no such path exists within
maxNodesExpanded expansions.
start is always treated as passable (even if its grid cell is 0 or the
cell is in blockedCells) — actors physics-pushed onto a wall still get a
valid origin.
