Fixes, added unit tests, all working well now
Minor API change, but we're keeping our version in sync with the target native version so #yolo. Fixes #1 Fixes #2 Converted all WinDivert tests to individual unit tests, all passing now. Added additional tests to make sure checksum calculation matched the calculation of an external library (not ideal not coding it ourselves, but if two libs can agree then that's OK for me).
