Random Outcome Command Java

Create a command that can generate either an analong or directional redstone output.

For example a command such as /randomOutput [type=analog,min=1,max=10] could generate a redstone output level somewhere between 1 and 10 every time it's activated.

Also, you could have /randomOutput [type=directional,directionsPossible=3] might have a command block pick one of 3 of it's sides and generate a signal in that direction. Obviously it has 4, maybe even a max of 6 sides, but it would make a lot of dungeon maker's lives a lot easier, rather than scour youtube for random output generators that no longer work 4 years after the design was posted, or rely on entity targeting. (Why again can't @r target entities in Java in 2020?)

This would be such a powerful addition to the game and make map-making a whole lot simpler, right?
