[temp][Editor] Handle NEID data format correctly

[AnrDaemon]

The difference is just that Blocks tag is replaced with Blocks16 which contains shorts instead of bytes, and there is no Add tag for the other 4 bytes added by forge, that's for the block IDs, and the difference for the metadata is that it's under Data16 instead of Data, and contains shorts instead of bytes(and the length is double, because the previous one was packing two metadatas into one byte, in NEID each short is one metadata)

Thanks Clepto from GTNH discord.
