At the moment, files are downloaded which intersect the region(s) of interest. Also, tiles are generated which intersect the region(s) of interest. However, given that a tile might overhang the edge of the region of interest, the files which are downloaded should encompass all tiles which might be generated.

Loop over the tiles first, and union their bounding boxes to provide the regions input for the download stage.
