Non thread-safe composter registration

[pau101]

I am reporting to you on behalf of Markus1002/Autumnity/issues/11

Currently Berry Good is registering compostability during the parallel dispatched common setup event. As this event is fired in parallel, multiple mods performing registration at this time create a race condition of whether an internal map corruption will occur, leading to startup crashes as seen in the linked issue. You should register compostability during relevant block/item registry events or utilize DeferredWorkQueue.
