mice 3.9.0

Major changes

• The D3() function in mice gave incorrect results. This version solves a problem in the calculation of the D3-statistic. See #226 and #228 for more details. The documentation explains why results from mice::D3() and mitml::testModels() may differ.
• The pool() function is now more forgiving when there is no glance() function (#233)
• It is possible to bypass remove.lindep() by setting eps = 0 (#225)

Minor changes

• Adds reference to Leacy's thesis
• Adds an example to the plot.mids() documentation
