option to generate FBS that contains activity cols and sector name cols

[catherinebirney]

generate an FBS that has columns of the original activity names and/or columns of the sector/naics names

can generate by running the example code

import flowsa.flowbysector
import pandas as pd

fbsmethod = 'Water_national_2015_m1'

fbs = pd.DataFrame(flowsa.flowbysector.FlowBySector.generateFlowBySector(
    fbsmethod,
    download_sources_ok=True,
    retain_activity_columns=True,
    append_sector_names=True
))

@bl-young do you think it would be better to implement these options through parameters in the FBS method yaml?

[bl-young]

hmmm, I could go either way. The sector names seems less important to put in the yaml because it doesn't change the structure of the output (just adds a column), whereas keeping the activity name means that it could be much larger.

Thanks - I will leave as-is then. My thoughts are also that adding the activity and sector name columns are not part of the method - and I would not want there to be two method files just so on one of them we can append the activity names.

@wadedavis13 Let us know if these changes meet your requirements - if so, we can pull these changes into the develop branch

These changes are ready to be pulled into develop/master. If @wadedavis13 needs additional changes, the code can be modified after the next flowsa release
