(Parity) Make Trial Chamber maps work on Java like they work on Bedrock

Right now, on Java Edition, a cartographer with the Trial Map on trade is single use. You buy one map from them and that's it. You can only ever get that one specific map from that cartographer. In order to get a new map, you have to make a new cartographer. On Bedrock, however, a cartographer will give you a new map to a new chamber if you've already gone to the chunks where the chamber on the map you already have is. The way it works on bedrock is significantly more convenient than on Java because of how it enables you to get directions to multiple chambers from a single villager, instead of having to get a new one every time.
