Difficulty Predicates

It'd be nice to have a predicate that can check world difficulty, as well as have location predicates be able to check local difficulty.

Some examples:

{
    "condition": "minecraft:difficulty_check",
    "predicate": {
        "game_type": [
            "peaceful",
            "easy",
            "normal",
            "hard"
        ],
        "moon_phase": {
            "min": 0.0
            "max": 1.0
        },
        "is_hardcore": false
    }
}

{
    "condition": "minecraft:location_check",
    "predicate": {
        "chunk": {
            "inhabited_time": {
                "min": 1
            }
            "local_difficulty": {
                "min": 0.0
                "max": 6.75
            },
            "clamped_local_difficulty": {
                "min": 0.0
                "max": 1.0
            }
        }
    }
}

{
    "condition": "minecraft:entity_properties",
    "entity": "this",
    "predicate": {
        "location": {
            "chunk": {
                "clamped_local_difficulty": 1.0
            }
        }
    }
}
