+ Specification for managing the initialisation and de-initialisation of skylight nibble arrays:
+
+ Skylight nibble initialisation requires that non-empty chunk sections have 1 radius nibbles non-null.
+
+ This presents some problems, as vanilla is only guaranteed to have 0 radius neighbours loaded when editing blocks.
+ However starlight fixes this so that it has 1 radius loaded. Still, we don't actually have guarantees
+ that we have the necessary chunks loaded to de-initialise neighbour sections (but we do have enough to de-initialise
+ our own) - we need a radius of 2 to de-initialise neighbour nibbles.
+ How do we solve this?
+
+ Each chunk will store the last known "emptiness" of sections for each of their 1 radius neighbour chunk sections.
+ If the chunk does not have full data, then its nibbles are NOT de-initialised. This is because obviously the
+ chunk did not go through the light stage yet - or its neighbours are not lit. In either case, once the last
+ known "emptiness" of neighbouring sections is filled with data, the chunk will run a full check of the data
+ to see if any of its nibbles need to be de-initialised.
+
+ The emptiness map allows us to de-initialise neighbour nibbles if the neighbour has it filled with data,
+ and if it doesn't have data then we know it will correctly de-initialise once it fills up.
+
+ Unlike vanilla, we store whether nibbles are uninitialised on disk - so we don't need any dumb hacking
+ around those.
