  1. fix(cli): mitigate polygon intersection errors 

    Use clipline to reduce polygon when we don't care about degenerate edges. When we do care call
intersection to remove the degenerate edges.

Store image bounds not polygons in SourceMetadata and also store in CogJob. This reduces
floating-point errors when combining source imagery bounds into composite polygons.

Note:

The Martinez polygon-clipping libraries can suffer from errors when lines align. Other intersection
libraries are intractable for the size of coastline polygons.  A solution is to call intersection
after first calling clipline.
