Generate enclosures based on passed barriers.
Enclosures are areas enclosed from all sides by at least one type of

like rivers and other water bodies or coastline. Enclosures are a
result of polygonization of the ``primary_barrier`` and ``limit`` and its

Parameters
----------
primary_barriers : GeoDataFrame, GeoSeries
GeoDataFrame or GeoSeries containing primary barriers.
(Multi)LineString geometry is expected.
limit : GeoDataFrame, GeoSeries (default None)
GeoDataFrame or GeoSeries containing external limit of enclosures,

additional_barriers : GeoDataFrame
GeoDataFrame or GeoSeries containing additional barriers.
(Multi)LineString geometry is expected.
enclosure_id : str (default 'eID')
