- [X] Removes network pause/resume - [X] Adds back packet profiler - [X] Adds state machine to keep track and trace netstates - [X] Changes NetState.Running back to using an interlock exchange - [X] Adds preliminary packet throttling support ### Packet Throttling - `[GetThrottle <packetId>` to get the delay in milliseconds for that packet - `[SetThrottle <packetId> <delay>` to set the delay in milliseconds for that packet The settings are saved to `Configuration/throttles.json`
