This fuzz test generates random inputs for waypoint solvers to check if they can find a solution. If they can't, the debug info for the solver is dumped to the testcases directory. Another test loads those test cases, creates a solver from them, and checks that a solution is found. Obviously it won't be immediately, but it's a starting point for fixing the bug and serves as a regression test afterward.
