Allow for the selection of a range in the /data command.

It is right now possible to select and modify multiple items with the data command. It would be very interesting to instantly see if values are within a certain range.

So instead of doing
/execute as @e[type=minecraft:villager] if data entity @s Offers.Recipes[]
and storing items then comparing and then actually getting the actual items with a certain range of demand.

You could just do something along the lines of

/execute as @e[type=minecraft:villager] if data entity @s Offers.Recipes[{demand: -9999..0}]
