geometry search: priority for tile completeness or spatial coverage?

[johntruckenbrodt]

When defining a search geometry via aoi_geometry, the processor currently selects all tiles overlapping with this geometry for ARD processing. However, due to the overlap between tiles, more tiles than necessary could be processed if just considering spatial coverage.
For example, in the below case processing the left tile would suffice for fully covering the defined area (orange) but the right tile would also be processed. Perhaps a new configuration option is needed to leave the decision the the user.
