A power schedule measures how "interesting" a value is, and depending on
the calculated value spends more or less time mutating it.
AFL++ comes with several power schedules, initially ported from [AFLFast](https://github.com/mboehme/aflfast)
however modified to be more effective and several more modes added.

The most effective modes are `-p fast` (default) and `-p explore`.

This is a problem for afl-fuzz because when the forkserver is started we must know the map size already and it can't be changed later.
