Moved decoder level — Turing Complete Steam update #257714

In this patch the decoder level was changed and moved to an earlier more natural place. Your old decoder solution will still work but some of it might be outside the level boundaries. If this bothers you, just create a new circuit and solve it again. Also I apologize for deleting the byte subtractor component the other day without a prior heads up, since it must have broken some players circuits. That wont happen again without notice.
