Stack with newest

[Distolfix]

@OmerBenGera

I propose adding a new configuration option for item stack handling:
Stack with newest

What does this do?

Currently, by default, the plugin (like vanilla) tries to merge a newly dropped item into the item already on the ground within the merge radius.
The issue is that in certain setups e.g., bamboo farms an item can remain on the ground and fail to enter the hoppers. The result? You risk losing the entire harvest, because the item that lands on the hoppers can get pulled back up due to the merge radius.

With the option I’m proposing, the older item will merge into the newer one, not the other way around.
This ensures the flow never gets stuck: items left on the ground will “unstick” by merging into the latest drop, preventing harvest losses.

Performance considerations

This feature would require a small additional check, since the plugin needs to know which item was created last.
However, the implementation can be simple:
attach a timestamp to each stack and compare it during merge. The most recent item becomes the “primary” stack and remains alive, while older stacks merge into it

This will cause your entities to never reach the hopper, as they will always get stacked to items that are created.

@OmerBenGera No, because if the old one freezes they lose the entire harvest, while if the next one bugs out it still unlocks the previous one. I tested this with UltimateStacker and players loved it, but for other reasons I switched to this plugin, and it would be nice if it could integrate that
