feat: streaming geoparquet writes

[gadomski]

Closes #174. cc @hrodmn

Example usage, from the notebook update:

import itertools

iterator = itertools.batched(items, 499)

with rustac.geoparquet_writer(list(next(iterator)), "items-batched.parquet") as writer:
    for item_batch in iterator:
        writer.write(list(item_batch))


item_collection = await rustac.read("items-batched.parquet")
