/bind ,execute binding function when binding scoreboard object changed

The bind command can bind a function to a scoreboard object. When the scoreboard object changes, the bind command will be executed, and the changing values will be param of the function. Usage may like this:/bind ScoreboardObject FunctionID

I think this command can make datapack more strong and reduce problems in development of datapacks.And it also make datapack don't need to check scoreboard every tick, it can reduce the pressure of CPUs.

This is just my thought, maybe it is hard to reach, but i still hope Mojang think about it.

Thanks a lot!
