Add parameters for qualified business income and update to taxcalc 3.0

[Peter-Metz]

This PR adds five four parameters to Tax-Cruncher for calculation of the qualified business income deduction:

• pbusinc: Primary filer's business income
• sbusinc: Spouse's business income
• businc: Business income (see comment)
• sstb: Boolean for whether business income is from a professional services business
• w2paid: W-2 wages paid by business
• qualprop: Filer's share of qualified property

Also, this PR brings Tax-Cruncher up to speed with Tax-Calculator 3.0. Notably, this simplifies parameter processing within cs-config/ because of Tax-Calculator's adoption of Paramtools.

@hdoupe would you mind reviewing the changes related to CS?

@MattHJensen and @kpomerleau might be interested in the new QBID functionality

In the latest commits, I've consolidated pbusinc and sbusinc into businc. Previously, pbusinc translated to e00900p and sbusinc translated to e00900s. Now, businc translates to e26270.

The reason for this change is twofold:

1. Tax-Calculator uses e26270 in its test for QBID logic. I've adopted a very similar test for Tax-Cruncher that returns the same QBID amounts.
2. There is an input field in Tax-Cruncher, but no Tax-Calculator parameter, for passive S-corp income. However, by asking for passive and activate S-corp income separately in Tax-Cruncher, we can calculate total S-corp income (e02000) to pass to Tax-Calculator and avoid double counting.

Thanks a lot for the assist @hdoupe! I'll merge this today if no one has objections
