HUD_TxferPredictionData
Because we can predict an arbitrary number of frames before the server responds with an update, we need to be able to copy client side prediction data in
from the state that the server ack'd receiving, which can be anywhere along the predicted frame path ( i.e., we could predict 20 frames into the future and the server ack's
up through 10 of those frames, so we need to copy persistent client-side only state from the 10th predicted frame to the slot the server
update is occupying.
