ADD amplifier to (potion) blocked-effects

[DYNIUU]

Please add the ability to block amplifiers of potion effects to terrain flags.

This will allow you to block the overly strong effects of potions on selected areas or on the entire global while allowing you to use potions with amplifiers of, for example, 1

Adding this go flag will allow servers to be more optimized. We will not have to create special scripts or install some extra plugins.

example:
/rg flag -w "world" -h 6 __global__ SPEED:2

I hope this feature will be added in the next update.
