Voxel line trace

[Takao-7]

Implement raycasts through the voxel structure itself, which doesn't use UE4 line traces:

Use a threshold value where voxels are counted as air/solid.

Example use cases:

• Actual line trace (stop on first solid hit)
• Sweep trace: find all voxels in the path below/above the threshold
