* Additional GAGS configuration json verification (#59524) This standardizes how values are read from the json for greyscale layers so that error handling can check for some additional things: No extra keys in the json that are unknown No missing keys that a layer needs to work Values are the expected type for that key A variety of error messages have been added for various ways the json can be malformed and should hopefully provide good feedback for anyone working with greyscale configurations. * Additional GAGS configuration json verification Co-authored-by: Emmett Gaines <ninjanomnom@gmail.com>
