Farbfeld is an intermediate format that is easy to parse and emit.
Sent can use pipe + fork + exec. This is similar to how tar handles
compressed archives.

You will need the farbfeld tools somewhere in your PATH. The tools
currently handle conversion between png and ff but there is nothing
stopping you from also supporting jpg. This means that sent will also
automatically work with jpgs as well.
