Review abstraction of packet serialization / deserialization

Packet Review

Description

Actually, SaltyEmu implements a PacketSerialization class which includes everything and is mainly based on reflection, which is really slow.

I'd like to add possibilities for developers to implement both ways to use that :

• IPacketSerializer
• IPacketDeserializer

Those two interfaces should be used as "individual methods" for each packet

(1 packet = 1 serializer & 1 deserializer)

This will permit :

• OpenNos interoperability (as long as someone implement it on its source)
• NosCore interoperability (as long as NosCore is willing to implement the same packets and participate to ChickenAPI)
• SaltyEmu interoperability

Since this issue is only related to packets, it should not be hard to ask for participation from other projects (NosCore, SaltyEmu, OpenNos forks devs...)
