This sidesteps making a decision around implementing support for negative
skip_features
in #309 for now and simply disallows that, which would have been equivalent to the behavior prior to #282. We can add support for negative slicing at a different time, if we so choose.This raises a specific
ValueError
and expands tests to match. I also added checks for negativemax_features
and associated tests.
