Merge tiny sources to idealize source size during COG transcoding #81

Ideally images should be ~ 10,000 x 10,000 pixel sizes but sometimes we have sources in the 3601 x 3601 (SRTM) and even smaller sizes.

We should rely instead on the CloudOptimizedGeoTIFF (COG) range seeking in a single file versus looking for tons of individual files.

The root cause we're trying to solve for is the ratio of overview covers the majority of title versus grid size. We want to solve for the smallest overview to the minimum usable zoom.

Related to thumbnail generation in general.
