ASCII Art Size
The ASCII art is roughly 7k.
You can LZ4 compress it and decompress on the fly, saving 3k or
so even when factoring in the decompression code.
The problem is decompression is slower (pauses the music) and
can't be run at the same time as the music decompression is
happening unless we duplicate a lot of code.
May revisit if we need the room.
