Require kenjutsu 0.3.0 or greater

In kenjutsu 0.3.0, the old API was deprecated and functions got shuffled
around into new modules. To ensure that we can use the new, not
deprecated, API, we need to make sure we are using a version that
supports the new API. So we require kenjutsu 0.3.0 to ensure we have
access to this new API.
