# Voxels Chunk (version 1)
# Voxels Chunk (version 2)
Voxel regions layer chunk structure.
Values are separated for extRLE8 compression efficiency.
IDs and states are separated for extRLE16 compression efficiency.
File format BNF (RFC 5234):
```bnf
chunk = (65536*byte) block indices (most significant bytes)
(65536*byte) block indices (least significant bytes)
(65536*byte) block states (most significant bytes)
(65536*byte) block states (least significant bytes)
chunk = (65536*uint16) block ids
(65536*uint16) block states
uint16 = 2byte 16 bit little-endian unsigned integer
byte = %x00-FF 8 bit unsigned integer
```
