geopy 1.18.1

on Python PyPI

FIXED: GeoNames.reverse_timezone didn't process errors returned by API
and instead was always raising obscure KeyError exceptions.

FIXED: GeoNames.reverse_timezone raised KeyError for points which
don't have an assigned Olson timezone ID (e.g. Antarctica).
Now a valid geopy.Timezone is returned for such, where pytz timezone
is created as pytz.FixedOffset.

FIXED: GoogleV3.reverse_timezone raised KeyError for points which
don't have an assigned Olson timezone ID (e.g. Antarctica).
Now None is returned for such requests, as Google doesn't provide
any meaningful data there.
