[1pt] PR: Added features to aggregate_outputs.py

[BrianAvant]

Adding features to aggregate_outputs.py to resolve issue #295 and issue #294

Additions

• reprojecting grids to Web Mercator
• parallelize HUC6 aggregation
• changing grid blocksize from 256 to 1024 for faster postprocessing

Note

This feature branch is derived from dev-catfim-workflow so it needs to be merged in after PR #292

[BradfordBates-NOAA]

@BrianAvant-NOAA It looks like this branch has conflicts with dev. Could you please merge and then I'll review

[BradfordBates-NOAA]

After the last patch, this branch is behind dev. Can you please merge again

@BrianAvant-NOAA, a couple questions:

• Is there any change in usage in fim_run.sh? Any extra args?
• Is there any change to the metrics after projecting grids to Web Mercator?

@BradfordBates-NOAA

• you can check the changes in the Files changed section; I set the jobs arg for aggregate_fim_outputs.py to 4 with no user access because we need to optimize on the API. We can do that later.
• metrics are run on the HUC8s currently. Web Mercator is used to reproject the HUC6s Viz use.
