parallel: recent PD implementation flushes last samples upon EOF Catch up with the implementation of the "parallel" decoder, which now flushes previously accumulated information when the end of input data is seen. Which completes the last "item" (data pattern on the bus), and may complete another "word" (data value that spans several bus cycles).
parallel: adjust hex number format of expected PD output The parallel decoder got adjusted to emit annotations for "items" and "words" in a unified format (consistent width, leading zeroes). Adjust the test expectation to match the PD implementation.
