Clash between Shapely and other GEOS libraries

[eboyda]

This is an issue with external libraries.

There is a known clash between shapely and the GEOS libraries - osgeo and therefore possibly rasterio and gbdxtools. So far, importing shapley before the other libraries has
cured the problem here - and I think the reordering of imports in dg_grabber.py is the only place this explicitly impacts the code base. When working from the interpreter, I know have to import utilities.geobox.geobox before dg_grabber.

There is some thought that the clash lies between Homebrew python / gdal installations
and shapley. See: shapely/shapely#260

If an exception is thrown, it will typically come with a (somewhat cryptic) message of the form:
"Assertion failed: (0), function query, file AbstractSTRtree.cpp, line 287."
