parallel: flush accumulated data when input data is exhausted
The "parallel" decoder buffers the currently seen data pattern, and
defers annotation emission until the end position is known. Which is
why the last data pattern would not show up in the decoder's output.
See bug #292 and its duplicates for examples and concerns.
Catch the EOFError exception, and flush previously accumulated data.
It is yet to get determined whether a warning annotation is due. Most
probably not for "parallel" which merely visualizes data line states.
But other decoders which have the concept of frames shall NOT follow
this "parallel" decoder's naive approach, and claim that a frame had
completed although its end condition was never seen. Add a developer
TODO comment to raise awareness.
