hds.get_kstpkper() returns 0 based kstp,kper while hds.kstpkper returns one based.

hds.get_kstpkper() returns 0 based kstp,kper while hds.kstpkper returns one based. hds = fp.utils.binaryfile.HeadFile(r"my.hds")

Is there a good reason for this? If not I would think both should be 0 based like most other stuff in flopy?

Discussed briefly in #2000, may eventually consider deprecating 1-based indexed attributes more comprehensively, for now just clarified the docstrings
