This pr, per the discussion in #102 lead to a modification of how normalized weights are handled.
Previously, partial-overlap areas were just completely ignored such that normalized weights would always sum to 1 per target polygon.
With the change implemented here, normalized weights for partial-overlap will be less than one.
This has no affect on output in practice but improves clarity and allows a person to know if one of their target polygons has limited source data to inform the value that is being assigned to it.
