Bugfix release.

Fixes
When using warnings, the types are defined as globals and not inside the warnings package.

Minor update release.

API Changes
- `get_coordinates` is replaced by `get_coordinates_2d` and `get_coordinates_3d`.
- Geos accessor now also works on series of shapely data, wkt strings or wkb bytes.
- Renamed `from_geopandas` to `to_geos` as it now converts more types to geos.

New
- Added `force_2d`
- Added `force_3d`
- Added `to_shapely` on accessor
- Added `to_wkt` on accessor
- Added `to_wkb` on accessor

Cleaned up the repository, removing redundant code and fixing the documentation.

Major release becuase we made some breaking changes.
The biggest change is that everything is now accessed as a method and not a property.

API Changes
- Added "keyed" series and dataframes. Whenever a PyGEOS function returns a variable number of outputs per input, we can flatten them in a single Series/DataFrame and use the index to point to the original object (foreign key principle). Examples are shown in tutorial.

- All geos attributes are now accessed as methods. This makes for a more uniform API.

- Delegated functions can now have default arguments, which cannot be overwritten by the user. Some functions have a different output depending on arguments, so this functionality allows us to set those arguments to a certain fixed value.

- `geos.get_coordinates` is now a keyed dataframe instead of it returning the output unmodified. This does mean that we needed to fix the `include_z` argument to **True**.

New
- Added `geos.get_geometry` and `geos.get_parts`. They are both "keyed" series.

This is a minor bugfix release.

Changes
- `geos.simplify` is now a method instead of a property as it has extra arguments.
- `geos.get_interior_ring` is now a method instead of a property as it has extra arguments.

This is a minor bugfix release, where we fixed some issues which we missed in 1.0.0

Changes
- Added a `__version__` attribute with versioneer.
- Added `get_point` method, which was missing in previous release.
- Added `minimum_rotated_rectangle`. Note that this method already existed as `oriented_envelope`, but is exposed under this new name as well (undocumented). This is similar to PyGEOS.
