This commit basically copy-pastes the last commits from https://dev.s-ul.net/VeroxZik/segatools/-/commits/master to add OpenITHM LED support. Doesn't need to edit segatools.ini because the relevant config lines are already there for some reason. Tested with my OpenITHM controller and behaves exactly like the other fork.
