feat: add optional operating_area

This can be defined in planning configuration and should
define a larger area containing the region_of_interest.

The intention is the region_of_interest is the area for
which data is being collected. The operating_area is an
area the platforms should not stray outside.

This allows us to define small test areas without triggering
an abort if a platform crosses the boundary.
