After reading through the protocol code, I thought it needed a bit of a rework - there is room for improvement (remove unsafe code, more idiomatic rust, and better performance)

I played around a bunch with alternative designs for better performance (notably for decoding) but it may be too complicated to adopt one of those approaches right now. Essentially, there should be custom read that allows to retrieve the bytes that are being read, which would minimize allocations and copies (seebincode).

For now I will try to implement something that works and that fully implements theprotocol using 0 unsafe code and idiomatic Rust, I will look into the customRead later on
