I retrieving the Visium spot from a mask.

I found the procedure a little bit slow.
Is it possible to parallelize the following code?

# Determine which spots are within the mask
points_within_mask = points_df.apply(lambda row: mask_geometry.contains(Point(row['x'], row['y'])), axis=1)
spots_in_mask = points_df[points_within_mask]

Hi @tkcaccia, can you try out the polygon_query() API and tell us how it compares in terms of speed?
