feat: new plot height calculation

* issue: Plot-System throw an exception when a plot height is out of its MIN_WORLD_HEIGHT and MAX_WORLD_HEIGHT value.

* fix: I created a set threshold whether the plot is in bound of vanilla y-level or not, all plot out of bounds is then get catches and paste on MIN_WORLD_HEIGHT
