Let "/spreadplayers under maxHeight" use tilde notation

In 1.16, /spreadplayers was given the optional maxHeight parameter for the maximum height to place players at. However, this parameter only accepts exact integers!

What do you want done?

maxHeight should also accept tilde notation, just like most position-based commands.

Why do you want something done?

This would allow the maxHeight to vary based on the position of the caller, instead of always being an exact integer. Right now, you'd have to check the caller's height and run different commands on a case-by-case basis!

  For now you can attach a chain command block onto the end of the impulse / repeating with the command "execute as @s(The same as the selector in the original command) run tp @s ~ (Y) ~" or execute @s(The same as the selector in the original command) ~~~ tp @s ~ (Y) ~

  That works in some cases, but I'm using /spreadplayers because it automatically finds valid positions for entities to be placed that aren't in walls or over lava, which you can't be sure of if you just /tp them.

  I'd like to be able to randomly place an entity at a similar height to a player, but the player's height varies. When I say you'd have to check the caller's height and run different commands on a case-by-case basis, I mean having a bunch of different /spreadplayers for each range of heights. This is what I've done:

  /execute as @s[y=0,dy=16] run spreadplayers ~ ~ 0.0 10 under 16 @e[name=bar]

  /execute as @s[y=16,dy=16] run spreadplayers ~ ~ 0.0 10 under 32 @e[name=bar]

  /execute as @s[y=32,dy=16] run spreadplayers ~ ~ 0.0 10 under 48 @e[name=bar]

  etc, all the way to y256.

  This will place "bar" at a position no more than 16 blocks higher from the chosen player, and usually not much lower (for the most part).

  As far as I can tell, there's no simpler way to do this currently. If I don't include under <maxHeight>, it'll place "bar" at the highest y value possible. But I want to be running this command in the nether, so  "bar" will end up on top of the nether roof. If I use under 128, "bar" could end up in some nether caves up at y100 while the player is mining for netherite at y16. I'd prefer to place "bar" somewhere close, if possible. So I have the check for every 16 blocks.

  If <maxHeight> could take tilde notation, all those commands could be reduced to just one.
