Implement Offline Plant Growth

[Happy-Hop7]

This feature simulates plant growth in chunks that would typically remain static when unloaded.
Upon revisiting or reloading the chunk, plants resume growth as if the chunk had been consistently loaded.

Users can easily toggle this feature on or off in the config.yml file.

This enhancement is particularly beneficial for users in less frequented regions, enabling them to cultivate plants without the need for constant loading in the area.
Additionally, it ensures a level playing field by eliminating the advantage for users residing near heavily loaded areas, such as the spawn point."
