Why AMF doesn't handle sctp message with multiple goroutine?

as v3.0.6 now sctp message handler in AMF is implemented with single thread and
performance will be significantly degraded since sctp queue in AMF is so accumulated.

especially when multiple real UEs are connected simultaneously, it become more noticeable problem.

Why does not implement these with goroutine, are there kinds of implementation problems?

Now we focus on functionality, so performance is not our main concern.
