Motivation
Although the footprint files are rounded to 8 decimal places, when they are combined into a capture area this can create some co-ordinates with more than 8 decimal places, which we then need to round.
Modifications
Use Shapely to round the co-ordinates to 8 decimal places after merging the footprint geometries.
Verification
Unit test created, unit tests updated for new capture area rounding.
Manually compared capture-area-compare.zip.
