Add level where flag is behind a wall of LOSE tiles

[unbibium]

• One starting BABA tile
• An unbroken wall of the barrier tile is between starting BABA
• A structure of WALL tiles that traverses both sides of the barrier
• WALL IS STOP rule that can be disassembled immediately
• BABA IS YOU rule that can be edited eventually
• Immutable rules that FLAG IS WIN, and the barrier tile is LOSE.
  • possibly protect these rules with a different barrier tile.
• user wins by taking control of some tile on the other side of the barrier:
  • adding WALL IS BABA to existing BABA IS YOU rule
  • changing BABA IS YOU rule to WALL IS YOU rule

A level from the 2017 game meets these criteria and looks like this screenshot:

I came up with one but the DATA statement compression is still not good enough to make it fit in one line. i might have to break down and make the DATA statements span multiple lines or something.
