A slightly better compression, but sadly ruined by the larger decompression code.

Each character in the magic string represents an index into the input array. I need the variable z so that I only read from STDIN once.

I could save some cost from IO by writing a lambda accepting an array and returning a string. This requires an extra v at the end, because it's not getting a free newline from -p.
