using DynamicProgram so need to change build.gradle.

usage:
Villager plays Amethyst Chime sound when moving on Amethyst blocks.

so let a villager stand on 3 Amethyst blocks in a row,
build double piston to make villager move on Amethyst blocks,
and the timer for piston should be more than 20ticks(10gt) to make sure there's Amethyst Chime sound every push.
(if the server is lag you should increase the interval)

need a 20hz clock for sync with server.
then use /ccrackvillager clock "clock position" to crack RNG
use /ccrackvillager addgoal to add your desire trade result (and price)
and /ccrackvillager run to crack once
