Subject: add boost tuple include to fix build
Patch-mainline: Submitted pr#1345
References: boost 1.76 build failure

With boost 1.76, we see:
lib/engine/rs_ellipse.cpp:70:15: error: 'tuple' in namespace 'boost::math' does not name a template type
   70 |  boost::math::tuple<double, double, double> operator()(double const& z) const {
      |               ^~~~~

Fix this by including the proper boost header.
