Title: DOC: improve KroghInterpolator docstrings, fixing argument type error

Fixes a small issue in the `KroghInterpolator.derivative` docstring, which incorrectly claimed you could pass `der=None`. (This must have been copied from the `derivatives` method, which takes `der=None` to mean "all the derivatives.") Also clarifies vector-valued `yi`s in the introductory text.
