Hmm not sure why the step is failing :/ I included the serialization, using
my messy code in the Apache Sedona Spark.
I can run the following udf using Apache Sedona which runs SedonaDB
```python
import pyarrow as pa
import shapely
import geoarrow.pyarrow as ga
from sedonadb import udf
@udf.arrow_udf(ga.wkb(), [udf.GEOMETRY, udf.NUMERIC])
def shapely_udf(geom, distance):
geom_wkb = pa.array(geom.storage.to_array())
distance = pa.array(distance.to_array())
geom = shapely.from_wkb(geom_wkb)
result_shapely = shapely.buffer(geom, distance)
return pa.array(shapely.to_wkb(result_shapely))
```
which gives me the result as follows for my testing data
```
+--------------------+
| geom|
+--------------------+
|POLYGON ((14.3093...|
|POLYGON ((14.3177...|
|POLYGON ((14.3891...|
|POLYGON ((14.2185...|
|POLYGON ((14.3595...|
|POLYGON ((14.3855...|
|POLYGON ((14.2739...|
|POLYGON ((14.4047...|
|POLYGON ((14.3120...|
|POLYGON ((14.3630...|

I think the current MR is ready and I'll continue working on the worker and
Apache Sedona, SedonaDB strategy
let me know what do you think
