Make packets in PacketHistory stay the only for a limited time

[Morcules]

• Right now packets_completed stores packets that were completed.
• It exists to check whether packet was accidentally sent twice and to check if large packet was completed.
• To clear up memory, the goal is to track time when packet was completed using timeval and in a batch check every packet in history and if it was completed (#define PACKET_HISTORY_STORE_TIME | or something like that) ago, remove it from vector and allocator_free
• Packet History is manipulated inside process_packets.c

[Morcules]

• Every PACKET_HISTORY_STORE_TIME / x (#define some amount like 5) check packet history, and cleanup. Store the timeval inside process_packets.c outside of loop scope.
