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
