copy/paste old flowkey logic into a util function, add a struct of key and packet, make WriteNoCopy accept this instead of a slice

have createSession fill the sessionInfo.cancel field, have Conn use Conn.session.cancel instead of storing its own cancellation, this should prevent any of these things from being both nil and reachable at the same time

add Conn.ReadNoCopy and Conn.WriteNoCopy that transfer ownership of a slice instead of copying, have Read and Write use the NoCopy versions under the hood and just manage copying as needed

properly fix the memory errors, it was caused by a function returning and PutBytes-ing a buffer before a worker had a chance to decrypt the buffer, so it would GetBytes the same buffer by dumb luck and then get an illegal overlap

somehow this doesn't seem to deadlock or crash from buffer reuse (util.PutBytes), but I have no idea why it was doing that before and not now
