feat: Pcap or other file based "net" implementation for replaying/simulation

[theangryangel]

Whilst working on https://github.com/theangryangel/race_directord it's popping up that it would be helpful to have a sample recording of insim packets for a subset of testing.

1. Offline development
2. Not needing a real server to play with
3. Allows hot-code reloading/interruptions

It should:

• Honour timings
• Probably ignore write calls

I like this idea!

I should have a look if there is such a tool in the Node.js world too, because it would be useful for testing Node InSim as well.

You could probably do something with scapy if you want something quick for testing. I’m in 2 minds if anything without some level of insim understand is going to work quite right. But I might be wrong!

when I get an evening where the girls aren’t playing up I’m hoping I can bang this out quickly 😅
