func UTP

func UTP(_ context.Context, metadata *adapter.InboundContext, packet []byte) error

UTP detects if the packet is a uTP connection packet. For the uTP protocol specification, see

1. https://www.bittorrent.org/beps/bep_0029.html
2. https://github.com/bittorrent/libutp/blob/2b364cbb0650bdab64a5de2abb4518f9f228ec44/utp_internal.cpp#L112
