Avoiding a brutal throw when boost root finding algorithm does not find any in LevelSet

Avoiding a brutal throw when boost root finding algorithm does not find any (when ray tracing LevelSet surface nodes), in line with a change in behavior of newton-raphson method between Boost 1.71 and Boost 1.74.

If still possible, that would be great if this MR could make it into the release since Boost 1.74 seems to be the default in Ubuntu 22.04..
