Run the Fuzz Harness

Now we just run:

./fuzzer.exe

And start testing the driver! The first thing we'll see is that it runs really quite fast, which is great. If we let the fuzzer run long enough, it'll eventually decide to generate an input that overflows the buffer, but it may take some time because we currently have no feedback from the driver we're testing -- only from the fuzzer program itself. This is "dumb fuzzing" at its finest, and we'll walk through the various options to improve the situation, starting with the easiest.
