The Graphic size of PointSymbolizer is not converted to the radius

[boeckMt]

As described in the SLD spec

The Size element gives the absolute size of the graphic in pixels...

so the incoming size should be treated as diameter

https://github.com/NieuwlandGeo/SLDReader/blob/master/src/OlStyler.js#L185
const radius = Number(style.size) || 10;
should be
const size Number(style.size) || 10; const radius = size / 2;
