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.

These never get called at the moment, so we have no way of
guaranteeing that any existing implementations are even correct. If
we do decide to start emulating the coin blocker then we will need
to advance the API versions, which will (hopefully) force any
third-party devs to test their coin blocker code before opting in.
