this saves a considerable amount of memory.
we don't actually need this state array in PM4 anyway, since we don't support the client-side chunk cache yet.
when the time comes to support it, it'll be much more practical to cache binary states and copy bytes anyway, instead of doing it the current way, which is both slow and memory-intensive.
Measured footprint change: 9 MB -> 400 KB.
this allows saving about 4 MB of memory, because there are many blocks which have identical states, although they have different IDs.
this relies on a potentially risky assumption that the tags in knownStates won't be modified. If they are modified, the changes will influence all blockstates which share the tag.
However, I don't expect this to happen, and the 4 MB memory saving is substantial enough to be worth the risk.

this uses a (potentially bogus) assumption that the lowest mapped meta value associated with an ID is valid. I don't want to break this during a patch release, and this works for now.
In the future it would probably make more sense to bypass ItemTranslator entirely, and rely solely on the blockstate returned by RuntimeBlockMapping to fetch the correct ID. This is similar to how we serialize items for saving on disk in PM5.
this eliminates the performance issues described by #5719.

we may want to consider exposing a public API for this in the future, since it might be useful for plugins.
we can safely assume that:
- the inventory's max stack size won't change during the operation
- two items which stack together have the same max stack size
- the item's max stack size won't change during the operation
Since light population is required to make a chunk tickable, a chunk may not be tickable for some time if the async workers get backlogged.
The previous version of this system only cached the eligibility result if the result was a "yes", but we can also track it when it's a "no", rather than rechecking it every tick.
This change should improve performance in factions and similar gamemodes, which involve large maps with sparsely distributed players, where each player likely has an independent, non-overlapping ticking chunk circle.
We also ditch TickingChunkEntry in favour of multiple arrays to track the eligibility states. This allows us to avoid rechecking the (even cached) readiness of potentially thousands of chunks. If there are no ticking chunks to recheck, this reduces the cost of the selection process to zero.
this doesn't support editing the rear side of a sign, since the 1.12 format doesn't allow us to represent the rear text, and it would necessitate API breaks to support anyway.
However, we can quite trivially support APIs for the sign GUI, which plugins can use to enable editing signs. PocketMine-MP doesn't currently permit this, since it's currently an experimental feature in 1.20, but plugins can simply use Player->openSignEditor() to mimic it.
This is, however, a byproduct of the fact that APIs needed to be added in order to facilitate the use of OpenSignPacket in 1.19.80.
this uses the same dodgy hack used by CraftingTransaction, which assumes that getResultsFor() does not care about the crafting inputs.
While this is currently OK, since none of the currently-implemented recipes care about inputs anyway, it will become a problem when we implement shulker box recipes, so this needs to be addressed.
However, it can't be addressed without BC breaks, so this will have to be dealt with in PM5.

this is usually because of an uncaught exception interacting with a try...finally block.
This will normally result in a crash anyway, and we don't want to obscure the real error.
