An increase to local mob cap

A local surface monster mob cap of 8 and local cave monster mob cap of 8 makes for a dull adventure on hard mode. Simply getting food, well timed sleep, and going to get diamonds almost guarantees a cake walk for an average player. I feel a general increase to the local monster mob cap even if it's varying with difficulty would add a new level of difficulty to the game that the challenge seeking players desire. Also now that devices with under 768MB of RAM are no longer being offered support, i think this is a more plausible idea moving into the future of bedrock edition.
