This PR is giving access to the
rv_arraywithin custom functions to build more advanced stats.We are using zonal_stats within a project for the United Nations to calculate intersect areas and percentages. Because the nodata filter gets applied to the mask beforehand, we found it difficult to calculate the intersect percentage with custom functions. We resorted to calculating as a combination of metrics, see WFP-VAM/prism-app#893. But it would be great to have access to the rv_array to give users a bit more flexibility to implement more complex statistics.
This is an attempt to do just that :)
