Voronoi C++20 warnings

Compiling the most simple Voronoi code, at Visual Studio 2022 (V143), with C++20, gives a lot warnings.
Most warnings are about using operator '+' or '>' between float and enum.
I'll be glad if this was solved somehow. I would be happy to do a PR, but I need some guidance, because not all warnings lead to the source.

Heres the minimalistic code snippet:
```C++
#include
#include

using boost::polygon::voronoi_diagram;
typedef voronoi_diagram VD;
typedef boost::polygon::point_data Point;
void stub() {
VD vd;

std::vector points;
construct_voronoi(points.cbegin(), points.cend(), &vd);
}
```

Heres the warnings:
```c++
