This simple node finds the values of a volume grid at positions in the local space used in geometry nodes evaluation. There are three interpolation modes to choose how to mix values between neighboring voxels. For the implementation, first the values are sampled with the grid's type directly, then implicit type conversions are used to get the final type. This makes gives us flexibility in case there aren't exact matches in support between grid types and Blender types. Pull Request: https://projects.blender.org/blender/blender/pulls/118397
