This pull request incorporates new input data files produced by taxdata pull request 307. Because the new CBO projection has different inflation rates than before, many of the inflation-indexed policy parameters have changed. And, of course, there are changes in the extrapolated attributes of the filing units in the (unchanged) puf.csv and cps.csv.gz files.

The changes in aggregate income and payroll tax revenue implied by these input data modifications vary by year. So, for example, in 2017 the puf.csv income and payroll tax revenues are up by 2.08% and 1.33% respectively, while in 2019 they are up by only 0.57% and 0.01%, respectively. But in 2025, the puf.csv income and payroll tax revenues are down by 0.63% and 0.30% , respectively.

Use of the new CBO projection permits the last simulation year to be increased from 2028 to 2029.
