Listener addEvent deadlock

Hi we encounter a deadlock in the Listener on b18411364d1cac72422c53a4b254fad0c9061204 in the follow situation.

We have main thread (M) and an iceoryx listener thread (L) with the following execution trace 1..4;

1(M): M creates a new iceoryx client (C1) and call Listener::attatchEvent and then send a request (Req1).
2(L): We get the reply (Req1) and go into the ReplyHandler (H1). It recursive **lock m_events[2]**.
3(M): M creates a new iceoryx client (C2) and call Listener::attatchEvent, it **locks Listener::m_addEventMutex and block on m_events[2]**
4(L): H1 creates a new iceoryx client(C3) and call Listener::attatchEvent, it **blocks on Listener::m_addEventMutex** ==> **DEADLOCK**

By judging from the attatchEvent comments ("This method can be called from any thread concurrently without any restrictions!") this is an iceoryx bug.

Please advice

Best regards
