# Payload
#
# Each layer and other information are stored as a "payload"
# A payload is consisted as follows:
#
# Literal Description
# "\0pLd" Payload header [00, 70, 4C, 64]
# [4] Identifier. 4 lettres ASCII string
# [6] Uncompressed size of DEFLATEd binary (max size 256 TB)

# Layer count 3
... "WIRE"
... Uncompressed size of DEFLATEd payload
... Wire tiles data (MSB only)
Payload "TERR" -- world terrain data, concatenation of MSB and LSB arrays. In Haskell style: Deflate(MSB ++ LSB)
Uncompressed size will be 1.5x of (width * height)
<EOF>
Payload "WALL" -- world walls data, concatenation of MSB and LSB arrays. In Haskell style: Deflate(MSB ++ LSB)
Uncompressed size will be 1.5x of (width * height)
Payload "WIRE" -- world wires data
Uncompressed size will be as same as (width * height)
Payload "TdMG" -- world terrain damage data, array of: (Int48 tileAddress, Float32 damage)

* To read layers: you'll need to search for specific strings, namely ["TERR", "WALL", "WIRE"]
