Subject: [PATCH] SparklyPaper: Skip "MapItem#update()" if the map does not
have the CraftMapRenderer present
Original project: https://github.com/SparklyPower/SparklyPaper
Optimizes "image in map" maps, without requiring the map to be locked, which some old map plugins may not do
This has the disadvantage that the vanilla map data will never be updated while the CraftMapRenderer is not present, but that's not a huuuge problem for u
