Implement the option to export exposure data per Quadkey
Files of exported exposure data are too big for countries like the US, India or China. Even smaller countries like Japan need very big SpatiaLite files (>100GB). Because global data is often provided in a tiled manner, exposure-share should be extended to accept a Quadkey as parameter to define the area to be exported.
The Quadkey should then be translated into a geometry that is then used to select the area for the data to be exported.
