postInitialise

Called after both the create constructor and the load constructor.

Use this to initialise stuff which must always be initialised, like creating logistics groups (see io.github.pylonmc.rebar.block.base.RebarLogisticBlock).

Called before postLoad, after io.github.pylonmc.rebar.event.RebarBlockPlaceEvent, after RebarBlockDeserializeEvent, and before io.github.pylonmc.rebar.event.RebarBlockLoadEvent
