Remove chunk save reattempt patch

This patch does not appear to be doing anything useful, and may
hide errors.

Currently, the save logic does not run through this path either
so it did not do anything.

Additionally, properly implement support for handling
RegionFileSizeException in Moonrise.

+Subject: [PATCH] Add Wandering Trader spawn rate config options
+
+Adds config options for modifying the spawn rates of Wandering Traders.
+These values are all easy to understand and configure after a quick read of this
+page on the Minecraft wiki: https://minecraft.wiki/wiki/Wandering_Trader#Spawning
+Usages of the vanilla WanderingTraderSpawnDelay and WanderingTraderSpawnChance values
+in IWorldServerData are removed as they were only used in certain places, with hardcoded
+values used in other places.
