High-level API:
type Statistics struct { ... }
type Counts struct { TxPackets, TxBytes, RxPackets, RxBytes uint64 }
func (*Statistics) UpdateTx([]byte)
func (*Statistics) UpdateRx([]byte)
func (*Statistics) Extract() map[flowtrack.Tuple]Counts
The API accepts a []byte instead of a packet.Parsed so that a future
implementation can directly hash the address and port bytes,
which are contiguous in most IP packets.
This will be useful for a custom concurrent-safe hashmap implementation.
