When two threads are using a WorkQueue and the reader thread exits due to an error, it must call WorkQueue::finish() to wake up the writer thread. Otherwise, if the queue is full and the writer thread is waiting for a free slot, it could hang forever.
This can happen in pratice when decompressing a large, corrupted file that does not contain pzstd skippable frames.
