Short note on total payment calculation

When calculating the total dollar amounts payment calculation, the following details are considered in the GET /pdl/allprograms endpoint:

1. In CRP, the "Total CRP" sub program contains the total value of all CRP payments. Just for the purpose of calculating the total values, the other sub programs and sub-sub programs in that can be ignored.
2. In Crop Insurance, the column net_farmer_benefits_amount contain the amount value that should be used for the total payment calculation. The payment column value is NULL for that program.
