Geometry Nodes: Random Value for the node tree (replacing seed input)

Currently Geometry Nodes has a Random Value node that will output a random number for each point / position. However, if a user wants to have a single random value for the entire geometry tree then it has to be manually set as an exposed seed value. Which means when object with GN modifier is duplicated the seed value has to be manually changed. This proposes a random value generator for the entire tree, so that when object is duplicated it is automatically randomized.
