Separate Packet Serialization/Deserialization to allow custom format.

Interestingly, I believe Serde only serializes the exact enum variant required. If an enum variant requires less data than others to store, Serde will only store the minimum necessary to do so. More information here: serde-rs/serde#251

This would suggest that using serialized enums to send data is still relatively efficient.

I had a look at serde, you're right, it should be fine
