Describe your idea

When implementing spreads, the offset was offset for a single offset (for min and max), or minOffset and maxOffset. It would be easier to have it like this:

{
  "constant_example": [0, 0, 0],
  "range_example": {
    "min": [-1, -1, -1],
    "max": [1, 1, 1]
  }
}

In this example, constant_example and range_example are just placeholders for the config entry name.
This could be used not only for spreads but for multiple configs:

• spread offset
• island offset in world.json5 (a bit useless here but possible)
• item count in starter inventory (maybe a bit unfair, but hey, i don't judge)
• spawn height in spawn.json5
