Subject: [PATCH] ExperienceOrb merging/stacking API
Adds ExperienceOrbMergeEvent
Fired when the server is about to merge 2 experience orbs
Plugins can cancel this if they want to ensure experience orbs do not lose important
metadata such as spawn reason, or conditionally move data from source to target.

Subject: [PATCH] ExperienceOrb merging/stacking API and fixes
Adds an option for maximum exp value when merging orbs
Adds ExperienceOrbMergeEvent
Fired when the server is about to merge 2 experience orbs
as entities. Plugins can cancel it if they want to ensure experience orbs do not lose important
metadata such as spawn reason, or conditionally move data from source to target.
Fixes an issue where the stacked count was not taking into account
for mending repairs and when merging with spigot's merge-on-spawn
logic
