No raster loading

[dnomadb]

@ian29 is getting this error w/ fillfacets (while I am not w/ the same inputs) - the most probable reason is an empty array is loading from the raster.

Traceback (most recent call last):

ZeroDivisionError: integer division or modulo by zero

1. Figure out the cause of this error
2. Better handle these kind of errors

Cause was invalid raster windows. Fixed in https://github.com/mapbox/make-surface/pull/81
