+Subject: [PATCH] add boost tuple include to fix build
+
+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.
