+          Value of 01 (DEFLATE) is recommended for its faster compression

+# 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)
+#   [..]           DEFLATEd binary (begins with one of these: 0x789C, 0x78DA, 0x7801)
+#   "EndPYLd\xFF"  Payload footer  [45, 6E, 64, 50, 59, 4C, 64, FF]
+
+
+Payload "TERR" -- world terrain data in Uint16
+                  Uncompressed size will be 2x of (width * height)
+
+Payload "WALL" -- world walls data in Unit16
+                  Uncompressed size will be 2x of (width * height)
+
+Payload "TdMG" -- world terrain damage data, array of: (Int48 tileAddress, Float32 damage)
+                  Uncompressed size will be arbitrary (multiple of tens)
+
+Payload "WdMG" -- world walls damage data, array of: (Int48 tileAddress, Float32 damage)
+                  Uncompressed size will be arbitrary (multiple of tens)
+
+Payload "FlTP" -- world fluid types, array of: (Int48 tileAddress, Signed Int16 type)
+                  Uncompressed size will be arbitrary (multiple of eights)
+
+Payload "FlFL" -- world fluid fills, array of: (Int48 tileAddress, Float32 amount)
+                  Uncompressed size will be arbitrary (multiple of tens)
+                  If the 'amount' < 0.0001f (WorldSimulator.FLUID_MIN_MASS), the entry must be discarded
+
+Payload "WiNt" -- wiring nodes, in JSON format
+
+Payload "CtYP" -- conduit types, array of: (Int48 tileAddress, Uint32 bitarray)
+                  can hold 32 different wires simultaneously
+
+Payload "CfL0" -- conduit fills, aka size of liquid/gas packet, array of: (Int48 tileAddress, Float32 fill)
+                  CfL0..CfL9, CfLa..CfLf are available to store values for 16 different things.

+* To read layers: you'll need to search for specific strings, namely ["TERR", "WALL", "WIRE"]
+* It is possible that compressed data happen to replicate any of the internal identifiers
+  (e.g. "\0pLdTERR", "EndTEM\xFF\xFE", "EndPYLd\xFF"), but such probability is very low (0.000000000000000005421 %)
