Isabelle’s Lazy Message Protocol

I don’t know whether or not this is a super practical way of doing things but I’m lazy and it seems to work so gonna roll with it lol

segment size	usage
1 byte	u8 packet kind
1 byte	u8 encrypt flag
8 byte	u64 length of the packet contents
4 byte	CRC32 packet contents checksum
32 byte	SHA256 packet contents integrity check
`u64::MAX`	packet contents

packet kind has defined values for packets but leaves many open for user defined packets to be added to the protocol

byte	packet kind
`0x00`	message - a simple text packet
`0xff`	agreement - used to help generate an aggreed upon key

encrypt flag can be 0x00 for no encrypt or 0xff for ring AEAD symmetric encrypt
