roll: third_party/pigweed: pw_transfer: Send continue parameters for already recevied chunks

This changes the behavior of pw_transfer when a receiver receives a
chunk of data it already has. Instead of entering the recovery state,
slashing its window size, and requesting an immediate retransmission,
it instead simply sends a PARAMETERS_CONTINUE chunk with its current
offset and window end offset.

This is done to minimize back-and-forth between the transfer peers by
not automatically invalidating any in-flight packets, in case the
expected packet is already on the way.
