fix #92

[dockfries]

let's go!

Thank you for your contribution.

1. I'm concerned about old commits being present. Let's fix it so this PR only contains your changes.
2. Have you personally tested that the emulation works as expected with your changes?
3. I think the proposed changes should not affect PR_EmulateIncomingRPC, because BitStream RPC doesn't have a packetid at the beginning.
4. The bs->resetReadPointer() call can be removed if bs->SetReadOffset(8) is added.

1. I will reset the commit and recommit it.
2. I tested in my environment (samp-node) only packet, it works, and I believe that's the issue.
3. for rpc, i'm wrong, yes , no SetReadOffset is needed.
4. ok, removed resetReadPointer()

I couldn't find the source code about onReceivePacket (only network.hpp), and refer to legacy_network_impl.cpp
I just saw that open.mp calls SetReadOffset(8).
