ODR violations in struct RayParams

[thiagomacieira]

When compiling with LTO, GCC complains:

source/scenequery/src/SqBucketPruner.cpp:1205:16: warning: type ‘struct RayParams’ violates the C++ One Definition Rule [-Wodr]
 1205 |         struct RayParams
      |                ^
source/geomutils/src/mesh/GuBV4_CapsuleSweepAA.cpp:46:16: note: a different type is defined in another translation unit

If they can't be merged, then please rename one of the structs or place one or both of them inside an unnamed namespace.

The structures have been moved to anonymous namespaces. The change should appear in a future release.
