This node hashes various types into an integer. Note that hashes cannot generally used as unique identifiers because they are not guaranteed to be unique. It can be used to generate somewhat stable randomness though in cases where White Noise does not offer enough flexibility. It uses hash functions from BLI_noise.hh. These are also used in the White Noise node. Pull Request: https://projects.blender.org/blender/blender/pulls/110769
