Trim hazard raster to slice extents #120

Open thomas-fred opened 1 year ago

Chop up hazard rasters to slice grid -- should speed up intersection process for large analyses.

Currently global aqueduct flooding rasters are several GB uncompressed. For a large number of slices, a given slice is small in extent and yet we have to open the planet sized file to lookup the relevant hazard intensity values.
