geoarrow.rust.io.write_flatgeobuf() panics when writing data that contains nulls

[paleolimbot]

I can follow up with a more complete example, but when preparing geoarrow-data I tried to write the example files, all of which contain nulls. When I try to write such a file I get:

pyo3_runtime.PanicException: called `Option::unwrap()` on a `None` value

Hmm.. it would be nice to see a traceback of exactly where this happens. Do you have a fuller example out of the box?

import geoarrow.pyarrow as ga
from geoarrow.rust.io import write_flatgeobuf
import pyarrow as pa

table = pa.table({"geometry": ga.as_geoarrow(["POINT (0 1)", None])})
write_flatgeobuf(table, "foofy.fgb")
#> PanicException: called `Option::unwrap()` on a `None` value

...the backtrace isn't useful because I think the debug symbols were stripped from the wheel?
