pcr: Add aflplusplus

The AFL website[1] states the following:
    Note: AFL hasn't been updated for a couple of years; while it
    should still work fine, a more complex fork with a variety of
    improvements and additional features, known as AFL++, is available
    from other members of the community and might be worth checking
    out.
