Basic modifications needed to read CPS input data

[martinholmer]

This pull request makes some basic changes to Tax-Calculator that are required in order to read and use CPS input data.

This pull request was developed using two CPS files generated in the taxdata repository after pull request 110 by @andersonfrailey was merged into the master branch: cps.csv.gz and cps_weights.csv.gz.

Using the code on this branch and the new CPS input files, a locally-generated conda taxcalc package, which includes the two CPS input files, produces the following aggregate tax results for current-law policy in 2020:

$ tc puf.csv 2020 --tables
You loaded data for 2009.
Tax-Calculator startup automatically extrapolated your data to 2020.

$ tc cps.csv 2020 --tables
You loaded data for 2014.
Tax-Calculator startup automatically extrapolated your data to 2020.

The CPS input data produces more payroll taxes, but less income taxes, than the PUF input data.

Tax-Calculator pull request #1484 is now complete and waiting for the cps.csv and cps_weights.csv files from the taxdata repository that will be included in this pull request. Per @MattHJensen instructions, this pull request will include CPS input files that exclude the C-TAM benefit variables. Those benefit variables will be added in subsequent taxdata and Tax-Calculator pull requests.
