We can probably drop the gdal, geos, proj & sparsehash dependencies from
libosmium2-dev, but it looks like Boost Interator has been upgraded from
an extra to important dependency in libosmium 2.3.0.
Or does the libboost-dev build dependency really belong in osmcoastline
despite it not using it directly?
