commit 18fb6475f5c9471ccafc3f9557d0c11bb3d2fa86

    Update AZ premium tax for 2021 release
    
    This is the last change specified in AZ Regulatory Bulletin 2016-02.
    That Bulletin specifies changes in premium-tax rates through 2025;
    see Arizona Revised Statutes Title 20, Insurance § 20-224 (B)(4)(f):
      "For premiums received in calendar year 2021 and for each subsequent
      calendar year, 1.70 percent"
    so no further change is contemplated to the rate committed here.
    
    The performance benchmarks changed insignificantly (they could hardly do
    otherwise). Incidentally, committing them elicited this:
     rewrite Speed_gcc_i686-w64-mingw32 (84%)
     rewrite Speed_gcc_x86_64-pc-linux-gnu (88%)
     rewrite Speed_gcc_x86_64-w64-mingw32 (88%)
    which is curious: the percentages apparently should be the dissimilarity
    index (number of changed lines divided by number of total lines,
    truncated to an integral percentage), but all three files have six
    changed lines out of seven, so "85%" would be expected for each. Of
    course it's no real problem that git actually reports slightly different
    dissimilarities here than its documentation implies.
