Sorting results by building_id

[nmerket]

Fixes #331.

Pull Request Description

Sorts results by building_id in the results csvs and parquets.

I didn't add a specific test for this one because it only gets unsorted on Eagle, so I couldn't duplicate the problem locally. I did run a test run on Eagle to confirm that it works now, though.

Looks like df.sort_index(inplace=True) was just out of place. Looks good.
