inventory from industrial facilities

[m-jamieson]

There are instances where generation is reported under NAICS code 22 in EIA form 923 and the generator is at an industrial facility. When electricity uses StEWI to pull other reported emissions, there is currently no way to see whether those emissions are reported for the rest of the industrial facility vs just the electricity generation. In cases where the emissions are for an industrial facility this can produce inaccurate inventories. For example, there is solar generation at an Intel facility in Arizona. The NEI inventory for this facility is actually for semiconductor manufacturing as indicated by its NAICS code (or general electronics) and reports very high SF6 emissions, which makes sense for this type of facility, but it makes no sense for solar generation.

To avoid this issue, we need to pull in facility NAICS information as done here in flowsa and filter non-electricity-generation flows out.
