Describe the issue

We decided to change the API for pairwise_linestring_distance in 22.12 (iirc) and drop the six unique arrays in favor of taking two GeoSeries instead.

This breaks the pairwise_linestring_distance example in users.ipynb because that example takes advantage of converting the type of a set of polygons into a set of linestrings, which relied on using the six argument API method for pairwise_linestring_distance.

The solution is to convert the polygon series to a linestring series using the GeoColumn constructor, as below.

x = cuspatial.GeoSeries([
    Polygon([[0, 1], [2, 3], [4, 5]]),
    Polygon([[6, 7], [8, 9], [10, 11]])
])

import cudf
import cupy as cp
y = cuspatial.core._column.geocolumn.GeoColumn(
    (
        cudf.Series(),
        cudf.Series(),
        cudf.Series(x._column.polygons._column.base_children[1]),
        cudf.Series()
    ),
    cuspatial.core._column.geocolumn.GeoMeta({
        "input_types": cp.repeat(cp.array(cuspatial.core._column.geometa.Feature_Enum.LINESTRING.value), len(x)),
        "union_offsets": cp.arange(len(x))
    })
)
geometry = cuspatial.GeoSeries(y)
