Improve seed based feature search to not load chunk (#5760)
This is done by returning the center location of the chunk at the height
 of the input location when the target chunk isn't loaded already which
 is exact enough for most use cases and will get more precise once the
 player is close enough for the chunk being loaded anyways.

As this might lead to less precise locations a config option to enable
 the sync loading of the chunks is provided.

Subject: [PATCH] Fix curing zombie villager discount exploit
This fixes the exploit used to gain absurd trading discounts with infecting
and curing a villager on repeat by simply resetting the relevant part of
the reputation when it is cured.
